+## Releases
+
+Cluster API uses [GitHub milestones](https://github.com/kubernetes-sigs/cluster-api/milestones) to track releases.
+
+- Minor versions CAN be planned and scheduled twice in a calendar year.
+  - Each minor version is preceded with one or more planning session.
+  - Planning consists of one or more backlog grooming meetings, roadmap amendments,
+    and CAEP proposal reviews.
+- Patch versions CAN be planned and scheduled each month for each of the currently supported series (usually N and N-1).
+- Code freeze is in effect 72 hours (3 days) before a release.
+  - Maintainers should communicate the code freeze date at a community meeting preceding the code freeze date.
+  - Only critical bug fixes may be merged in between freeze & release.
+    - Each bug MUST be associated with an open issue and properly triaged.
+    - PRs MUST be approved by at least 2 project maintainers.
+      - First approver should `/approve` and `/hold`.
+      - Second approver should `/approve` and `/hold cancel`.
+  - [E2E Test grid](https://testgrid.k8s.io/sig-cluster-lifecycle-cluster-api#capi%20e2e%20tests) SHOULD be green before cutting a release.
+- Dates in a release are approximations and always subject to change.
+- `Next` milestone is for work that has been triaged, but not prioritized/accepted for any release.
+
+## Proposal process (CAEP)
+
+The Cluster API Enhacement Proposal is the process this project uses to adopt new features, changes to the APIs, changes to contracts between components, or changes to CLI interfaces.
+
+The [template](https://github.com/kubernetes-sigs/cluster-api/blob/master/docs/proposals/YYYYMMDD-template.md), and accepted proposals live under [docs/proposals](https://github.com/kubernetes-sigs/cluster-api/tree/master/docs/proposals).
+
+- Proposals or requests for enhacements (RFEs) MUST be associated with an issue.
+  - Issues can be placed on the roadmap during planning if there is one or more folks
+    that can dedicate time to writing a CAEP and/or implementating it after approval.
+- A proposal SHOULD be introduced and discussed during the weekly community meetings,
+  [Kubernetes SIG Cluster Lifecycle mailing list](https://groups.google.com/forum/#!forum/kubernetes-sig-cluster-lifecycle),
+  or [discuss forum](https://discuss.kubernetes.io/c/contributors/cluster-api/).
+  - Submit and discuss proposals using a collaborative writing platform, preferably Google Docs, share documents with edit permissions with the [Kubernetes SIG Cluster Lifecycle mailing list](https://groups.google.com/forum/#!forum/kubernetes-sig-cluster-lifecycle).
+- A proposal in a Google Doc MUST turn into a [Pull Request](https://github.com/kubernetes-sigs/cluster-api/pulls).
+- Proposals MUST be merged and in `implementable` state to be considered part of a major or minor release.

-## What is the Cluster API?
+## ✨ What is the Cluster API?
 
 Cluster API is a Kubernetes sub-project focused on providing declarative APIs and tooling to simplify provisioning, upgrading, and operating multiple Kubernetes clusters.
 
 Started by the Kubernetes Special Interest Group (SIG) Cluster Lifecycle, the Cluster API project uses Kubernetes-style APIs and patterns to automate cluster lifecycle management for platform operators. The supporting infrastructure, like virtual machines, networks, load balancers, and VPCs, as well as the Kubernetes cluster configuration are all defined in the same way that application developers operate deploying and managing their workloads. This enables consistent and repeatable cluster deployments across a wide variety of infrastructure environments.
 
-__NB__: Cluster API is still in a prototype stage while we get
-feedback on the API types themselves. All of the code here is to experiment with
-the API and demo its abilities, in order to drive more technical feedback to the
-API design. Because of this, all of the codebase is rapidly changing.
+### ⚙️ Providers

-Cluster API can be extended to support any infrastructure provider (AWS, Azure, vSphere, etc.) or bootstrap provider (kubeadm is default) you need. There is a growing list of [supported providers](https://cluster-api.sigs.k8s.io/reference/providers.html) available.

-
-// Package v1beta1 defines the v1beta1 version of the kubeadm configuration file format.
-// This version graduates the configuration format to BETA and is a big step towards GA.
-//
-//A list of changes since v1alpha3:
-//	- "apiServerEndpoint" in InitConfiguration was renamed to "localAPIEndpoint" for better clarity of what the field
-//	represents.
-//	- Common fields in ClusterConfiguration such as "*extraArgs" and "*extraVolumes" for control plane components are now moved
-//	under component structs - i.e. "apiServer", "controllerManager", "scheduler".
-//	- "auditPolicy" was removed from ClusterConfiguration. Please use "extraArgs" in "apiServer" to configure this feature instead.
-//	- "unifiedControlPlaneImage" in ClusterConfiguration was changed to a boolean field called "useHyperKubeImage".
-//	- ClusterConfiguration now has a "dns" field which can be used to select and configure the cluster DNS addon.
-//	- "featureGates" still exists under ClusterConfiguration, but there are no supported feature gates in 1.13.
-//	See the Kubernetes 1.13 changelog for further details.
-//	- Both "localEtcd" and "dns" configurations now support custom image repositories.
-//	- The "controlPlane*"-related fields in JoinConfiguration were refactored into a sub-structure.
-//	- "clusterName" was removed from JoinConfiguration and the name is now fetched from the existing cluster.
-//
-// Migration from old kubeadm config versions
-//
-// Please convert your v1alpha3 configuration files to v1beta1 using the "kubeadm config migrate" command of kubeadm v1.13.x
-// (conversion from older releases of kubeadm config files requires older release of kubeadm as well e.g.
-//	kubeadm v1.11 should be used to migrate v1alpha2 to v1alpha2; kubeadm v1.12 should be used to translate v1alpha2 to v1alpha3)
-//
-// Nevertheless, kubeadm v1.13.x will support reading from v1alpha3 version of the kubeadm config file format, but this support
-// will be dropped in the v1.14 release.
-//
-// Basics
-//
-// The preferred way to configure kubeadm is to pass an YAML configuration file with the --config option. Some of the
-// configuration options defined in the kubeadm config file are also available as command line flags, but only
-// the most common/simple use case are supported with this approach.
-//
-// A kubeadm config file could contain multiple configuration types separated using three dashes (“---”).
-//
-// kubeadm supports the following configuration types:
-//
-//     apiVersion: kubeadm.k8s.io/v1beta1
-//     kind: InitConfiguration
-//
-//     apiVersion: kubeadm.k8s.io/v1beta1
-//     kind: ClusterConfiguration
-//
-//     apiVersion: kubelet.config.k8s.io/v1beta1
-//     kind: KubeletConfiguration
-//
-//     apiVersion: kubeproxy.config.k8s.io/v1alpha2
-//     kind: KubeProxyConfiguration
-//
-//     apiVersion: kubeadm.k8s.io/v1beta1
-//     kind: JoinConfiguration
-//
-// To print the defaults for "init" and "join" actions use the following commands:
-//  kubeadm config print init-defaults
-//  kubeadm config print join-defaults
-//
-// The list of configuration types that must be included in a configuration file depends by the action you are
-// performing (init or join) and by the configuration options you are going to use (defaults or advanced customization).
-//
-// If some configuration types are not provided, or provided only partially, kubeadm will use default values; defaults
-// provided by kubeadm includes also enforcing consistency of values across components when required (e.g.
-// cluster-cidr flag on controller manager and clusterCIDR on kube-proxy).
-//
-// Users are always allowed to override default values, with the only exception of a small subset of setting with
-// relevance for security (e.g. enforce authorization-mode Node and RBAC on api server)
-//
-// If the user provides a configuration types that is not expected for the action you are performing, kubeadm will
-// ignore those types and print a warning.
-//
-// Kubeadm init configuration types
-//
-// When executing kubeadm init with the --config option, the following configuration types could be used:
-// InitConfiguration, ClusterConfiguration, KubeProxyConfiguration, KubeletConfiguration, but only one
-// between InitConfiguration and ClusterConfiguration is mandatory.
-//
-//     apiVersion: kubeadm.k8s.io/v1beta1
-//     kind: InitConfiguration
-//     bootstrapTokens:
-//         ...
-//     nodeRegistration:
-//         ...
+// Package v1beta1 contains a mirror of kubeadm API v1beta1 API, required because it is not possible to import k/K.
 //
-// The InitConfiguration type should be used to configure runtime settings, that in case of kubeadm init
-// are the configuration of the bootstrap token and all the setting which are specific to the node where kubeadm
-// is executed, including:
+// IMPORTANT: Do not change these files!
+// IMPORTANT: only for KubeadmConfig serialization/deserialization, and should not be used for other purposes.
 //
-// - NodeRegistration, that holds fields that relate to registering the new node to the cluster;
-// use it to customize the node name, the CRI socket to use or any other settings that should apply to this
-// node only (e.g. the node ip).
-//
-// - LocalAPIEndpoint, that represents the endpoint of the instance of the API server to be deployed on this node;
-// use it e.g. to customize the API server advertise address.
-//
-//     apiVersion: kubeadm.k8s.io/v1beta1
-//     kind: ClusterConfiguration
-//     networking:
-//         ...
-//     etcd:
-//         ...
-//     apiServer:
-//       extraArgs:
-//         ...
-//       extraVolumes:
-//         ...
-//     ...
-//
-// The ClusterConfiguration type should be used to configure cluster-wide settings,
-// including settings for:
-//
-// - Networking, that holds configuration for the networking topology of the cluster; use it e.g. to customize
-// node subnet or services subnet.
-//
-// - Etcd configurations; use it e.g. to customize the local etcd or to configure the API server
-// for using an external etcd cluster.
-//
-// - kube-apiserver, kube-scheduler, kube-controller-manager configurations; use it to customize control-plane
-// components by adding customized setting or overriding kubeadm default settings.
-//
-//    apiVersion: kubeproxy.config.k8s.io/v1alpha2
-//    kind: KubeProxyConfiguration
-//       ...
-//
-// The KubeProxyConfiguration type should be used to change the configuration passed to kube-proxy instances deployed
-// in the cluster. If this object is not provided or provided only partially, kubeadm applies defaults.
-//
-// See https://kubernetes.io/docs/reference/command-line-tools-reference/kube-proxy/ or https://godoc.org/k8s.io/kube-proxy/config/v1alpha1#KubeProxyConfiguration
-// for kube proxy official documentation.
-//
-//    apiVersion: kubelet.config.k8s.io/v1beta1
-//    kind: KubeletConfiguration
-//       ...
-//
-// The KubeletConfiguration type should be used to change the configurations that will be passed to all kubelet instances
-// deployed in the cluster. If this object is not provided or provided only partially, kubeadm applies defaults.
-//
-// See https://kubernetes.io/docs/reference/command-line-tools-reference/kubelet/ or https://godoc.org/k8s.io/kubelet/config/v1beta1#KubeletConfiguration

-// Package v1beta2 defines the v1beta2 version of the kubeadm configuration file format.
-// This version improves on the v1beta1 format by fixing some minor issues and adding a few new fields.
-//
-// A list of changes since v1beta1:
-//	- "certificateKey" field is added to InitConfiguration and JoinConfiguration.
-//	- "ignorePreflightErrors" field is added to the NodeRegistrationOptions.
-//	- The JSON "omitempty" tag is used in a more places where appropriate.
-//	- The JSON "omitempty" tag of the "taints" field (inside NodeRegistrationOptions) is removed.
-//	See the Kubernetes 1.15 changelog for further details.
-//
-// Migration from old kubeadm config versions
-//
-// Please convert your v1beta1 configuration files to v1beta2 using the "kubeadm config migrate" command of kubeadm v1.15.x
-// (conversion from older releases of kubeadm config files requires older release of kubeadm as well e.g.
-//	kubeadm v1.11 should be used to migrate v1alpha2 to v1alpha2; kubeadm v1.12 should be used to translate v1alpha2 to v1alpha3;
-//	kubeadm v1.13 or v1.14 should be used to translate v1alpha3 to v1beta1)
-//
-// Nevertheless, kubeadm v1.15.x will support reading from v1beta1 version of the kubeadm config file format.
-//
-// Basics
-//
-// The preferred way to configure kubeadm is to pass an YAML configuration file with the --config option. Some of the
-// configuration options defined in the kubeadm config file are also available as command line flags, but only
-// the most common/simple use case are supported with this approach.
-//
-// A kubeadm config file could contain multiple configuration types separated using three dashes (“---”).
-//
-// kubeadm supports the following configuration types:
-//
-//     apiVersion: kubeadm.k8s.io/v1beta2
-//     kind: InitConfiguration
-//
-//     apiVersion: kubeadm.k8s.io/v1beta2
-//     kind: ClusterConfiguration
-//
-//     apiVersion: kubelet.config.k8s.io/v1beta1
-//     kind: KubeletConfiguration
-//
-//     apiVersion: kubeproxy.config.k8s.io/v1alpha2
-//     kind: KubeProxyConfiguration
-//
-//     apiVersion: kubeadm.k8s.io/v1beta2
-//     kind: JoinConfiguration
-//
-// To print the defaults for "init" and "join" actions use the following commands:
-//  kubeadm config print init-defaults
-//  kubeadm config print join-defaults
-//
-// The list of configuration types that must be included in a configuration file depends by the action you are
-// performing (init or join) and by the configuration options you are going to use (defaults or advanced customization).
-//
-// If some configuration types are not provided, or provided only partially, kubeadm will use default values; defaults
-// provided by kubeadm includes also enforcing consistency of values across components when required (e.g.
-// cluster-cidr flag on controller manager and clusterCIDR on kube-proxy).
-//
-// Users are always allowed to override default values, with the only exception of a small subset of setting with
-// relevance for security (e.g. enforce authorization-mode Node and RBAC on api server)
-//
-// If the user provides a configuration types that is not expected for the action you are performing, kubeadm will
-// ignore those types and print a warning.
-//
-// Kubeadm init configuration types
-//
-// When executing kubeadm init with the --config option, the following configuration types could be used:
-// InitConfiguration, ClusterConfiguration, KubeProxyConfiguration, KubeletConfiguration, but only one
-// between InitConfiguration and ClusterConfiguration is mandatory.
-//
-//     apiVersion: kubeadm.k8s.io/v1beta2
-//     kind: InitConfiguration
-//     bootstrapTokens:
-//         ...
-//     nodeRegistration:
-//         ...
+// Package v1beta2 contains a mirror of kubeadm API v1beta2 API, required because it is not possible to import k/K.
 //
-// The InitConfiguration type should be used to configure runtime settings, that in case of kubeadm init
-// are the configuration of the bootstrap token and all the setting which are specific to the node where kubeadm
-// is executed, including:
+// IMPORTANT: Do not change these files!
+// IMPORTANT: only for KubeadmConfig serialization/deserialization, and should not be used for other purposes.
 //
-// - NodeRegistration, that holds fields that relate to registering the new node to the cluster;
-// use it to customize the node name, the CRI socket to use or any other settings that should apply to this
-// node only (e.g. the node ip).
-//
-// - LocalAPIEndpoint, that represents the endpoint of the instance of the API server to be deployed on this node;
-// use it e.g. to customize the API server advertise address.
-//
-//     apiVersion: kubeadm.k8s.io/v1beta2
-//     kind: ClusterConfiguration
-//     networking:
-//         ...
-//     etcd:
-//         ...
-//     apiServer:
-//       extraArgs:
-//         ...
-//       extraVolumes:
-//         ...
-//     ...
-//
-// The ClusterConfiguration type should be used to configure cluster-wide settings,
-// including settings for:
-//
-// - Networking, that holds configuration for the networking topology of the cluster; use it e.g. to customize
-// node subnet or services subnet.
-//
-// - Etcd configurations; use it e.g. to customize the local etcd or to configure the API server
-// for using an external etcd cluster.
-//
-// - kube-apiserver, kube-scheduler, kube-controller-manager configurations; use it to customize control-plane
-// components by adding customized setting or overriding kubeadm default settings.
-//
-//    apiVersion: kubeproxy.config.k8s.io/v1alpha2
-//    kind: KubeProxyConfiguration
-//       ...
-//
-// The KubeProxyConfiguration type should be used to change the configuration passed to kube-proxy instances deployed
-// in the cluster. If this object is not provided or provided only partially, kubeadm applies defaults.
-//
-// See https://kubernetes.io/docs/reference/command-line-tools-reference/kube-proxy/ or https://godoc.org/k8s.io/kube-proxy/config/v1alpha1#KubeProxyConfiguration
-// for kube proxy official documentation.
-//
-//    apiVersion: kubelet.config.k8s.io/v1beta1
-//    kind: KubeletConfiguration
-//       ...
-//
-// The KubeletConfiguration type should be used to change the configurations that will be passed to all kubelet instances
-// deployed in the cluster. If this object is not provided or provided only partially, kubeadm applies defaults.
-//
-// See https://kubernetes.io/docs/reference/command-line-tools-reference/kubelet/ or https://godoc.org/k8s.io/kubelet/config/v1beta1#KubeletConfiguration

+                      ObjectMeta is embedded in `Machine.Spec`, `MachineDeployment.Template`
+                      and `MachineSet.Template`, which are not top-level Kubernetes
+                      objects. Given that metav1.ObjectMeta has lots of special cases
+                      and read-only fields which end up in the generated CRD validation,
+                      having it as a subset simplifies the API and some issues that
+                      can impact user experience. \n During the [upgrade to controller-tools@v2](https://github.com/kubernetes-sigs/cluster-api/pull/1054)
+                      for v1alpha2, we noticed a failure would occur running Cluster
+                      API test suite against the new CRDs, specifically `spec.metadata.creationTimestamp
+                      in body must be of type string: \"null\"`. The investigation
+                      showed that `controller-tools@v2` behaves differently than its
+                      previous version when handling types from [metav1](k8s.io/apimachinery/pkg/apis/meta/v1)
+                      package. \n In more details, we found that embedded (non-top
+                      level) types that embedded `metav1.ObjectMeta` had validation
+                      properties, including for `creationTimestamp` (metav1.Time).
+                      The `metav1.Time` type specifies a custom json marshaller that,
+                      when IsZero() is true, returns `null` which breaks validation
+                      because the field isn't marked as nullable. \n In future versions,
+                      controller-tools@v2 might allow overriding the type and validation
+                      for embedded types. When that happens, this hack should be revisited."

+                                user experience. \n During the [upgrade to controller-tools@v2](https://github.com/kubernetes-sigs/cluster-api/pull/1054)
+                                for v1alpha2, we noticed a failure would occur running
+                                Cluster API test suite against the new CRDs, specifically
+                                `spec.metadata.creationTimestamp in body must be of
+                                type string: \"null\"`. The investigation showed that
+                                `controller-tools@v2` behaves differently than its
+                                previous version when handling types from [metav1](k8s.io/apimachinery/pkg/apis/meta/v1)
+                                package. \n In more details, we found that embedded
+                                (non-top level) types that embedded `metav1.ObjectMeta`
+                                had validation properties, including for `creationTimestamp`
+                                (metav1.Time). The `metav1.Time` type specifies a
+                                custom json marshaller that, when IsZero() is true,
+                                returns `null` which breaks validation because the
+                                field isn't marked as nullable. \n In future versions,
+                                controller-tools@v2 might allow overriding the type
+                                and validation for embedded types. When that happens,
+                                this hack should be revisited."

+                    type are discouraged because of difficulty describing its usage
+                    when embedded in APIs.  1. Ignored fields.  It includes many fields
+                    which are not generally honored.  For instance, ResourceVersion
+                    and FieldPath are both very rarely valid in actual usage.  2.
+                    Invalid usage help.  It is impossible to add specific help for
+                    individual usage.  In most embedded usages, there are particular     restrictions
+                    like, "must refer only to types A and B" or "UID not honored"
+                    or "name must be restricted".     Those cannot be well described
+                    when embedded.  3. Inconsistent validation.  Because the usages
+                    are different, the validation rules are different by usage, which
+                    makes it hard for users to predict what will happen.  4. The fields
+                    are both imprecise and overly precise.  Kind is not a precise
+                    mapping to a URL. This can produce ambiguity     during interpretation
+                    and require a REST mapping.  In most cases, the dependency is
+                    on the group,resource tuple     and the version of the actual
+                    struct is irrelevant.  5. We cannot easily change it.  Because
+                    this type is embedded in many locations, updates to this type     will
+                    affect numerous schemas.  Don''t make new APIs embed an underspecified
+                    API type they do not control. Instead of using this type, create
+                    a locally provided and used type that is well-focused on your
+                    reference. For example, ServiceReferences for admission registration:

+                    type are discouraged because of difficulty describing its usage
+                    when embedded in APIs.  1. Ignored fields.  It includes many fields
+                    which are not generally honored.  For instance, ResourceVersion
+                    and FieldPath are both very rarely valid in actual usage.  2.
+                    Invalid usage help.  It is impossible to add specific help for
+                    individual usage.  In most embedded usages, there are particular     restrictions
+                    like, "must refer only to types A and B" or "UID not honored"
+                    or "name must be restricted".     Those cannot be well described
+                    when embedded.  3. Inconsistent validation.  Because the usages
+                    are different, the validation rules are different by usage, which
+                    makes it hard for users to predict what will happen.  4. The fields
+                    are both imprecise and overly precise.  Kind is not a precise
+                    mapping to a URL. This can produce ambiguity     during interpretation
+                    and require a REST mapping.  In most cases, the dependency is
+                    on the group,resource tuple     and the version of the actual
+                    struct is irrelevant.  5. We cannot easily change it.  Because
+                    this type is embedded in many locations, updates to this type     will
+                    affect numerous schemas.  Don''t make new APIs embed an underspecified
+                    API type they do not control. Instead of using this type, create
+                    a locally provided and used type that is well-focused on your
+                    reference. For example, ServiceReferences for admission registration:

+# clusterctl alpha rollout
+
+The `clusterctl alpha rollout` command manages the rollout of a Cluster API resource. It consists of several sub-commands which are documented below. 
+
+<aside class="note">
+
+<h1> Valid Resource Types </h1>
+
+Currently, only the following Cluster API resources are supported by the rollout command:
+
+- machinedeployment
+
+</aside>
+
+### Restart 
+
+Use the `restart` sub-command to force an immediate rollout. Note that rollout refers to the replacement of existing machines with new machines using the desired rollout strategy (default: rolling update). For example, here the MachineDeployment `my-md-0` will be immediately rolled out:
+
+```
+clusterctl alpha rollout restart machinedeployment/my-md-0
+```
+
+### Undo
+
+Use the `undo` sub-command to rollback to an earlier revision. For example, here the MachineDeployment `my-md-0` will be rolled back to revision number 3. If the `--to-revision` flag is omitted, the MachineDeployment will be rolled back to the revision immediately preceding the current one. If the desired revision does not exist, the undo will return an error.
+
+```
+clusterctl alpha rollout undo machinedeployment/my-md-0 --to-revision=3
+```
+
+### Pause/Resume
+
+Use the `pause` sub-command to pause a Cluster API resource. The command is a NOP if the resource is already paused. Note that internally, this command sets the `Paused` field within the resource spec (e.g. MachineDeployment.Spec.Paused) to true. 
+
+```
+clusterctl alpha rollout pause machinedeployment/my-md-0
+```
+
+Use the `resume` sub-command to resume a currently paused Cluster API resource. The command is a NOP if the resource is currently not paused. 
+
+```
+clusterctl alpha rollout resume machinedeployment/my-md-0
+```
+
+<aside class="note warning">
+
+<h1> Warning </h1>
+
+Paused resources will not be reconciled by a controller. By resuming a resource, we allow it to be reconciled again.

-KNOWN BUG:
-
-Deleting an infrastructure component from a namespace _that share

-in erroneous deletion of cluster scoped objects such as `ClusterRole` and
-`ClusterRoleBindings` that share the same namespace prefix.
-

-as `foo` and `foobar` are fine however namespaces such as `foo` and `foo-bar`
-are not.
-
-For example,
-
-1. Init an infrastructure provider in namespace `foo` and `foo-bar`.

-    clusterctl init --infrastructure aws --watching-namespace foo --target-namespace foo
-    clusterctl init --infrastructure aws --watching-namespace foo-bar --target-namespace foo-bar

+# clusterctl generate cluster
+
+The `clusterctl generate cluster` command returns a YAML template for creating a workload cluster.
+
+For example
+
+```
+clusterctl generate cluster my-cluster --kubernetes-version v1.16.3 --control-plane-machine-count=3 --worker-machine-count=3 > my-cluster.yaml
+```
+
+Geenerates a YAML file named `my-cluster.yaml` with a predefined list of Cluster API objects; Cluster, Machines,
+Machine Deployments, etc. to be deployed in the current namespace (in case, use the `--target-namespace` flag to
+specify a different target namespace).
+
+Then, the file can be modified using your editor of choice; when ready, run the following command
+to apply the cluster manifest.
+
+```
+kubectl apply -f my-cluster.yaml
+```
+
+### Selecting the infrastructure provider to use
+
+The `clusterctl generate cluster` command uses smart defaults in order to simplify the user experience; in the example above,
+it detects that there is only an `aws` infrastructure provider in the current management cluster and so it automatically
+selects a cluster template from the `aws` provider's repository.
+
+In case there is more than one infrastructure provider, the following syntax can be used to select which infrastructure
+provider to use for the workload cluster:
+
+```
+clusterctl generate cluster my-cluster --kubernetes-version v1.16.3 \
+    --infrastructure aws > my-cluster.yaml
+```
+
+or
+
+```
+clusterctl generate cluster my-cluster --kubernetes-version v1.16.3 \
+    --infrastructure aws:v0.4.1 > my-cluster.yaml
+```
+
+### Flavors
+
+The infrastructure provider authors can provide different types of cluster templates, or flavors; use the `--flavor` flag
+to specify which flavor to use; e.g.
+
+```
+clusterctl generate cluster my-cluster --kubernetes-version v1.16.3 \
+    --flavor high-availability > my-cluster.yaml
+```
+
+Please refer to the providers documentation for more info about available flavors.
+
+### Alternative source for cluster templates
+
+clusterctl uses the provider's repository as a primary source for cluster templates; the following alternative sources
+for cluster templates can be used as well:
+
+#### ConfigMaps
+
+Use the `--from-config-map` flag to read cluster templates stored in a Kubernetes ConfigMap; e.g.
+
+```
+clusterctl generate cluster my-cluster --kubernetes-version v1.16.3 \
+    --from-config-map my-templates > my-cluster.yaml
+```
+
+Also following flags are available `--from-config-map-namespace` (defaults to current namespace) and `--from-config-map-key`
+(defaults to `template`).
+
+#### GitHub or local file system folder
+
+Use the `--from` flag to read cluster templates stored in a GitHub repository or in a local file system folder; e.g.
+
+```
+clusterctl generate cluster my-cluster --kubernetes-version v1.16.3 \
+   --from https://github.com/my-org/my-repository/blob/master/my-template.yaml > my-cluster.yaml
+```
+
+or
+
+```
+clusterctl generate cluster my-cluster --kubernetes-version v1.16.3 \
+   --from ~/my-template.yaml > my-cluster.yaml
+```
+
+### Variables
+
+If the selected cluster template expects some environment variables, the user should ensure those variables are set in advance.
+
+E.g. if the `AWS_CREDENTIALS` variable is expected for a cluster template targeting the `aws` infrastructure, you
+should ensure the corresponding environment variable to be set before executing `clusterctl generate cluster`.
+
+Please refer to the providers documentation for more info about the required variables or use the
+`clusterctl generate cluster --list-variables` flag to get a list of variables names required by a cluster template.
+
+The [clusterctl configuration](./../configuration.md) file can be used as alternative to environment variables.

-## Upgrading a Multi-tenancy management cluster
-
-[Multi-tenancy](init.md#multi-tenancy) for Cluster API means a management cluster where multiple instances of the same
-provider are installed, and this is achieved by multiple calls to `clusterctl init`, and in most cases, each one with
-different environment variables for customizing the provider instances.
-
-In order to upgrade a multi-tenancy management cluster, and preserve the instance specific settings, you should do
-the same during upgrades and execute multiple calls to `clusterctl upgrade apply`, each one with different environment
-variables.
-
-For instance, in case of a management cluster with n>1 instances of an infrastructure provider, and only one instance
-of Cluster API core provider, bootstrap provider and control plane provider, you should:
-
-Run once `clusterctl upgrade apply` for the core provider, the bootstrap provider and the control plane provider;
-this can be achieved by using the `--core`, `--bootstrap` and `--control-plane` flags followed by the upgrade target
-for each one of those providers, e.g.
-
-```shell
-clusterctl upgrade apply --management-group capi-system/cluster-api \
-    --core capi-system/cluster-api:v0.3.1 \
-    --bootstrap capi-kubeadm-bootstrap-system/kubeadm:v0.3.1 \
-    --control-plane capi-kubeadm-control-plane-system/kubeadm:v0.3.1
-```
-
-Run `clusterctl upgrade apply` for each infrastructure provider instance, using the `--infrastructure` flag,
-taking care to provide different environment variables for each call (as in the initial setup), e.g.
-
-Set the environment variables for instance 1 and then run:
-
-```shell
-clusterctl upgrade apply --management-group capi-system/cluster-api \
-    --infrastructure instance1/docker:v0.3.1
-```
-
-Afterwards, set the environment variables for instance 2 and then run:
-
-```shell
-clusterctl upgrade apply --management-group capi-system/cluster-api \

+
+Similarly, it is possible to override the default version installed by clusterctl by configuring:
+
+```yaml
+cert-manager:
+  ...
+  version: "v1.1.1"
+```
+
+For situations when resources are limited or the network is slow, the cert-manager wait time to be running can be customized by adding a field to the clusterctl config file, for example:

+```yaml
+
+```yaml
+cert-manager:

+  timeout: 15m
+```
+
+The value string is a possibly signed sequence of decimal numbers, each with optional fraction and a unit suffix, such as "300ms", "-1.5h" or "2h45m". Valid time units are "ns", "us" (or "µs"), "ms", "s", "m", "h".

+This file is a single YAML with _all_ the components required for installing the provider itself (CRDs, Controller, RBAC etc.).

+* Core providers release a file called `core-components.yaml`
 * Infrastructure providers release a file called `infrastructure-components.yaml`
 * Bootstrap providers release a file called ` bootstrap-components.yaml`
 * Control plane providers release a file called `control-plane-components.yaml`
 
-#### Shared and instance components
-
-The objects contained in a component YAML file can be divided in two sets:
-
-- Instance specific objects, like the Deployment for the controller, the ServiceAccount used for running the controller
-  and the related RBAC rules.
-- The objects that are shared among all the provider instances, like e.g. CRDs, ValidatingWebhookConfiguration or the
-  Deployment implementing the web-hook servers and related Service and Certificates.
-
-As per the Cluster API contract, all the shared objects are expected to be deployed in a namespace named `capi-webhook-system`
-(if applicable). 
-
-clusterctl implements a different lifecycle for shared resources e.g.
-- ensuring that the version of the shared objects for each provider matches the latest version installed in the cluster.
-- ensuring that deleting an instance of a provider does not destroy shared resources unless explicitly requested by the user.  
-
 #### Target namespace
 
 The instance components should contain one Namespace object, which will be used as the default target namespace
 when creating the provider components.
 
 All the objects in the components YAML MUST belong to the target namespace, with the exception of objects that

+  * All the objects if the CRD scope is `Cluster`.
+* All the `ConfigMap` objects from the namespace being moved.
+* All the `Secret` objects from the namespace being moved and from the namespaces where infrastructure providers are installed.
+
+After completing discovery, `clusterctl move` moves to the target cluster only the objects discovered in the previous phase
+that are compliant with one of the following rules:
+  * The object is directly or indirectly linked to a `Cluster` object (linked through the `OwnerReference` chain).
+  * The object is a secret containing a user provided certificate (linked to a `Cluster` object via a naming convention).

+Note. `clusterctl.cluster.x-k8s.io/move` and `clusterctl.cluster.x-k8s.io/move-hierarchy` labels could be applied

+# MachinePool  Controller
+
+![](../../../images/cluster-admission-machinepool-controller.png)
+
+The MachinePool controller's main responsibilities are:
+
+* Setting an OwnerReference on each MachinePool object to:
+    * The associated Cluster object.
+    * The associated BootstrapConfig object.
+    * The associated InfrastructureMachinePool object.
+* Copy data from `BootstrapConfig.Status.DataSecretName` to `MachinePool.Spec.Template.Spec.Bootstrap.DataSecretName` if
+`MachinePool.Spec.Template.Spec.Bootstrap.DataSecretName` is empty.
+* Setting NodeRefs on MachinePool instances to be able to associate them with kubernetes nodes.
+* Deleting Nodes in the target cluster when the associated MachinePool instance is deleted.
+* Keeping the MachinePool's Status object up to date with the InfrastructureMachinePool's Status object.
+* Finding Kubernetes nodes matching the expected providerIDs in the workload cluster.
+
+After the machine pool controller sets the OwnerReferences on the associated objects, it waits for the bootstrap
+and infrastructure objects referenced by the machine to have the `Status.Ready` field set to `true`. When
+the infrastructure object is ready, the machine pool controller will attempt to read its `Spec.ProviderIDList` and
+copy it into `MachinePool.Spec.ProviderIDList`.
+
+The machine pool controller uses the kubeconfig for the new workload cluster to watch new nodes coming up.
+When a node appears with a `Node.Spec.ProviderID` in `MachinePool.Spec.ProviderIDList`, the machine pool controller
+increments the number of ready replicas. When all replicas are ready and the infrastructure ref is also
+`Ready`, the machine pool controller marks the machine pool as `Running`.
+
+## Contracts
+
+### Cluster API
+
+Cluster associations are made via labels.
+
+#### Expected labels
+
+| what | label | value | meaning |
+| --- | --- | --- | --- |
+| MachinePool | `cluster.x-k8s.io/cluster-name` | `<cluster-name>` | Identify a machine pool as belonging to a cluster with the name `<cluster-name>`|
+
+### Bootstrap provider
+
+The BootstrapConfig object **must** have a `status` object.
+
+To override the bootstrap provider, a user (or external system) can directly set the `MachinePool.Spec.Bootstrap.DataSecretName`
+field. This will mark the machine as ready for bootstrapping and no bootstrap data secret name will be copied from the
+BootstrapConfig object.
+
+#### Required `status` fields
+
+The `status` object **must** have several fields defined:
+
+* `ready` - a boolean field indicating the bootstrap config data is generated and ready for use.
+* `dataSecretName` - a string field referencing the name of the secret that stores the generated bootstrap data.
+
+#### Optional `status` fields
+
+The `status` object **may** define several fields that do not affect functionality if missing:
+
+* `failureReason` - a string field explaining why a fatal error has occurred, if possible.
+* `failureMessage` - a string field that holds the message contained by the error.
+
+Example:
+
+```yaml
+kind: MyBootstrapProviderConfig
+apiVersion: bootstrap.cluster.x-k8s.io/v1alpha3
+status:
+    ready: true
+    dataSecretName: "MyBootstrapSecret"
+```
+
+### Infrastructure provider
+
+The InfrastructureMachinePool object **must** have both `spec` and `status` objects.
+
+#### Required `spec` fields
+
+The `spec` object **must** have at least one field defined:
+
+* `providerIDList` - the list of cloud provider IDs identifying the instances.
+
+#### Required `status` fields
+
+The `status` object **must** have at least one field defined:
+
+* `ready` - a boolean field indicating if the infrastructure is ready to be used or not.
+
+#### Optional `status` fields
+
+The `status` object **may** define several fields that do not affect functionality if missing:
+
+* `failureReason` - is a string that explains why a fatal error has occurred, if possible.
+* `failureMessage` - is a string that holds the message contained by the error.
+
+Example:
+```yaml
+kind: MyMachinePool
+apiVersion: infrastructure.cluster.x-k8s.io/v1alpha3
+spec:
+    providerIDList:
+      - cloud:////my-cloud-provider-id-0
+      - cloud:////my-cloud-provider-id-1
+status:
+    ready: true
+```
+
+### Secrets

+# Support running multiple instances of the same provider
+
+Up until v1alpha3, the need of supporting [multiple credentials](../../../reference/glossary.md#multi-tenancy) was addressed by running multiple
+instances of the same provider, each one with its own set of credentials while watching different namespaces.
+
+However, running multiple instances of the same provider proved to be complicated for several reasons:
+
+- Complexity in packaging providers: CustomResourceDefinitions (CRD) are global resources, these may have a reference
+  to a service that can be used to convert between CRD versions (conversion webhooks). Only one of these services should
+  be running at any given time, this requirement led us to previously split the webhooks code to a different deployment
+  and namespace.
+- Complexity in deploying providers, due to the requirement to ensure consistency of the management cluster, e.g.
+  controllers watching the same namespaces.
+- The introduction of the concept of management groups in clusterctl, with impacts on the user experience/documentation.
+- Complexity in managing co-existence of different versions of the same provider while there could be only
+  one version of CRDs and webhooks. Please note that this constraint generates a risk, because some version of the provider
+  de-facto were forced to run with CRDs and webhooks deployed from a different version.
+
+Nevertheless, we want to make it possible for users to choose to deploy multiple instances of the same providers,
+in case the above limitations/extra complexity are acceptable for them.
+
+## Contract
+
+In order to make it possible for users to deploy multiple instances of the same provider:
+
+- Providers MUST support the `--namespace` flag in their controllers.
+- Providers MUST support the `--watch-filter` flag in their controllers.
+
+⚠️ Users selecting this deployment model, please be aware:
+
+- Support should be considered best-effort.
+- Cluster API (incl. every provider managed under `kubernetes-sigs`) won't release a specialized components file
+  supporting the scenario described above; however, users should be able to create such deployment model from
+  the `/config` folder.
+- Cluster API (incl. every provider managed under `kubernetes-sigs`) testing infrastructure won't run test cases
+  with multiple instances of the same provider.
+
+In conclusion, giving the increasingly complex task that is to manage multiple instances of the same controllers,
+the Cluster API community may only provide best effort support for users that choose this model.
+
+As always, if some members of the community would like to take on the responsibility of managing this model,
+please reach out through the usual communication channels, we'll make sure to guide you in the right path.

+# Cluster API v1alpha3 compared to v1alpha4
+
+## Minimum Go version
+
+- The Go version used by Cluster API is now Go 1.16+
+  - In case cloudbuild is used to push images, please upgrade to `gcr.io/k8s-testimages/gcb-docker-gcloud:v20210331-c732583`
+    in the cloudbuild YAML files.
+
+## Controller Runtime version
+
+- The Controller Runtime version is now v0.9.+
+
+## Controller Tools version (if used)
+
+- The Controller Tools version is now v0.6.+
+
+## Kind version
+
+- The KIND version used for this release is v0.11.x
+
+## :warning: Go Module changes :warning:
+
+- The `test` folder now ships with its own Go module `sigs.k8s.io/cluster-api/test`.
+- The module is going to be tagged and versioned as part of the release.
+- Folks importing the test e2e framework or the docker infrastructure provider need to import the new module.
+  - When imported, the test module version should always match the Cluster API one.
+  - Add the following line in `go.mod` to replace the cluster-api dependency in the test module (change the version to your current Cluster API version):
+  ```
+  replace sigs.k8s.io/cluster-api => sigs.k8s.io/cluster-api v0.4.x
+  ```
+- The CAPD go module in test/infrastructure/docker has been removed.
+
+## Klog version
+
+- The klog package used has been upgraded to v2.5.x. It is recommended that
+  all providers also switch to using v2.
+
+  - Change `import k8s.io/klog` to `import k8s.io/klog/v2`
+  - Change `import k8s.io/klog/klogr` to `import k8s.io/klog/v2/klogr`
+  - Update `go.mod` to `k8s.io/klog/v2 v2.5.0`
+  - Run `go mod tidy` to ensure all dependencies are updated.
+
+## The controllers.DeleteNodeAnnotation constant has been removed
+
+- This annotation `cluster.k8s.io/delete-machine` was originally deprecated a while ago when we moved our types under the `x-k8s.io` domain.
+
+## The controllers.DeleteMachineAnnotation has been moved to v1alpha4.DeleteMachineAnnotation
+
+- This annotation was previously exported as part of the controllers package, instead this should be a versioned annotation under the api packages.
+
+## Align manager flag names with upstream Kubernetes components
+
+- Rename `--metrics-addr` to `--metrics-bind-addr`
+- Rename `--leader-election` to `--leader-elect`
+
+## util.ManagerDelegatingClientFunc has been removed
+
+This function was originally used to generate a delegating client when creating a new manager.
+
+Controller Runtime v0.9.x now uses a `ClientBuilder` in its Options struct and it uses
+the delegating client by default under the hood, so this can be now removed.
+
+## Use to Controller Runtime's new fake client builder
+
+- The functions `fake.NewFakeClientWithScheme` and `fake.NewFakeClient` have been deprecated.
+- Switch to `fake.NewClientBuilder().WithObjects().Build()` instead, which provides a cleaner interface
+  to create a new fake client with objects, lists, or a scheme.
+
+## Multi tenancy
+
+Up until v1alpha3, the need of supporting multiple credentials was addressed by running multiple
+instances of the same provider, each one with its own set of credentials while watching different namespaces.
+
+Starting from v1alpha4 instead we are going require that an infrastructure provider should manage different credentials,
+each one of them corresponding to an infrastructure tenant.
+
+see [Multi-tenancy](../architecture/controllers/multi-tenancy.md) and [Support multiple instances](../architecture/controllers/support-multiple-instances.md) for
+more details.
+
+Specific changes related to this topic will be detailed in this document.
+
+## Change types with arrays of pointers to custom objects
+
+The conversion-gen code from the `1.20.x` release onward generates incorrect conversion functions for types having arrays of pointers to custom objects. Change the existing types to contain objects instead of pointer references.
+
+## Optional flag for specifying webhook certificates dir
+Add optional flag `--webhook-cert-dir={string-value}` which allows user to specify directory where webhooks will get tls certificates.
+If flag has not provided, default value from `controller-runtime` should be used.
+
+## Required kustomize changes to have a single manager watching all namespaces and answer to webhook calls
+
+In an effort to simplify the management of Cluster API components, and realign with Kubebuilder configuration,
+we're requiring some changes to move all webhooks back into a single deployment manager, and to allow Cluster
+API watch all namespaces it manages.
+For a `/config` folder reference, please use the testdata in the Kubebuilder project: https://github.com/kubernetes-sigs/kubebuilder/tree/master/testdata/project-v3/config
+
+**Pre-requisites**
+
+Provider's `/config` folder has the same structure of  `/config` folder in CAPI controllers.
+
+**Changes in the `/config/webhook` folder:**
+
+1. Edit the `/config/webhook/kustomization.yaml` file:
+    - Remove the `namespace:` configuration

+    ```
+    - Verify that feature flags required by your container are properly set
+      (as it was in `/config/webhook/manager_webhook_patch.yaml`).
+1. Edit the `/config/manager/manager_auth_proxy_patch.yaml` file:
+    - Remove the patch for the container with name `manager`
+1. Move the following files to the `/config/default` folder
+    - `/config/manager/manager_auth_proxy_patch.yaml`
+    - `/config/manager/manager_image_patch.yaml`
+    - `/config/manager/manager_pull_policy.yaml`
+
+**Changes in the `/config/default` folder:**
+1. Create a file named `/config/default/kustomizeconfig.yaml` with the following content:
+   ```
+   # This configuration is for teaching kustomize how to update name ref and var substitution
+   varReference:
+   - kind: Deployment
+     path: spec/template/spec/volumes/secret/secretName
+   ```
+1. Edit the `/config/default/kustomization.yaml` file:
+    - Add the `namePrefix` and the `commonLabels` configuration values copying values from the `/config/kustomization.yaml` file
+    - In the `bases:` list, add the following items:
+      ```
+      - ../crd
+      - ../certmanager
+      - ../webhook
+      ```
+    - Add the `patchesStrategicMerge:` list, with the following items:
+      ```
+      - manager_auth_proxy_patch.yaml

+      - manager_pull_policy.yaml
+      - manager_webhook_patch.yaml
+      - webhookcainjection_patch.yaml
+      ```
+    - Add a `vars:` configuration using the value from the temporary file created while modifying `/config/webhook/kustomization.yaml`
+    - Add the `configurations:` list with the following items:
+      ```

+
+**Other changes:**
+
+- makefile
+    - update all the references for `/config/manager/manager_image_patch.yaml` to `/config/default/manager_image_patch.yaml`
+    - update all the references for `/config/manager/manager_pull_policy.yaml` to `/config/default/manager_pull_policy.yaml`
+    - update all the call to `kustomize` targeting `/config` to target `/config/default` instead.
+- E2E config files
+    - update provider sources reading from `/config` to read from `/config/default` instead.
+- clusterctl-settings.json file
+    - if the `configFolder` value is defined, update from `/config` to `/config/default`.
+
+## Upgrade cert-manager to v1.1.0
+
+NB. instructions assumes "Required kustomize changes to have a single manager watching all namespaces and answer to webhook calls"
+should be executed before this changes.
+
+**Changes in the `/config/certmanager` folder:**
+
+1. Edit the `/config/certmanager/certificate.yaml` file and replace all the occurrences of `cert-manager.io/v1alpha2`
+   with `cert-manager.io/v1`
+
+**Changes in the `/config/default` folder:**
+
+1. Edit the `/config/default/kustomization.yaml` file and replace all the occurencies of
+   ```
+         kind: Certificate
+         group: cert-manager.io
+         version: v1alpha2
+   ```
+   with
+   ```
+         kind: Certificate
+         group: cert-manager.io
+         version: v1
+   ```
+## Support the cluster.x-k8s.io/watch-filter label and watch-filter flag.
+
+- A new label `cluster.x-k8s.io/watch-filter` provides the ability to filter the controllers to only reconcile objects with a specific label.
+- A new flag `watch-filter` enables users to specify the label value for the `cluster.x-k8s.io/watch-filter` label on controller boot.
+- The flag which enables users to set the flag value can be structured like this:
+  ```go
+  	fs.StringVar(&watchFilterValue, "watch-filter", "", fmt.Sprintf("Label value that the controller watches to reconcile cluster-api objects. Label key is always %s. If unspecified, the controller watches for all cluster-api objects.", clusterv1.WatchLabel))
+  ```
+- The `ResourceNotPausedAndHasFilterLabel` predicate is a useful helper to check for the pause annotation and the filter label easily:
+  ```go
+  c, err := ctrl.NewControllerManagedBy(mgr).
+		For(&clusterv1.MachineSet{}).
+		Owns(&clusterv1.Machine{}).
+		Watches(
+			&source.Kind{Type: &clusterv1.Machine{}},
+			handler.EnqueueRequestsFromMapFunc(r.MachineToMachineSets),
+		).
+		WithOptions(options).
+		WithEventFilter(predicates.ResourceNotPausedAndHasFilterLabel(ctrl.LoggerFrom(ctx), r.WatchFilterValue)).
+		Build(r)
+	if err != nil {
+		return errors.Wrap(err, "failed setting up with a controller manager")
+	}
+  ```
+
+## Required changes to have individual service accounts for controllers.
+
+1. Create a new service account such as:
+  ```yaml
+  apiVersion: v1
+  kind: ServiceAccount
+  metadata:
+    name: manager
+  namespace: system
+  ```
+2. Change the `subject` of the managers `ClusterRoleBinding` to match:
+  ```yaml
+  subjects:
+  - kind: ServiceAccount
+    name: manager
+    namespace: system
+  ```
+3. Add the correct `serviceAccountName` to the manager deployment:
+  ```yaml
+  serviceAccountName: manager
+  ```
+
+## Percentage String or Int API input will fail with a string different from an integer with % appended.
+
+`MachineDeployment.Spec.Strategy.RollingUpdate.MaxSurge`, `MachineDeployment.Spec.Strategy.RollingUpdate.MaxUnavailable` and `MachineHealthCheck.Spec.MaxUnhealthy` would have previously taken a String value with an integer character in it e.g "3" as a valid input and process it as a percentage value.
+Only String values like "3%" or Int values e.g 3 are valid input values now. A string not matching the percentage format will fail, e.g "3".
+
+## Required change to support externally managed infrastructure.
+
+- A new annotation `cluster.x-k8s.io/managed-by` has been introduced that allows cluster infrastructure to be managed
+  externally.
+- When this annotation is added to an `InfraCluster` resource, the controller for these resources should not reconcile
+  the resource.
+- The `ResourceIsNotExternallyManaged` predicate is a useful helper to check for the annotation and the filter the resource easily:
+  ```go
+  c, err := ctrl.NewControllerManagedBy(mgr).
+		For(&providerv1.InfraCluster{}).
+		Watches(...).
+		WithOptions(options).
+		WithEventFilter(predicates.ResourceIsNotExternallyManaged(ctrl.LoggerFrom(ctx))).
+		Build(r)
+	if err != nil {
+		return errors.Wrap(err, "failed setting up with a controller manager")
+	}
+  ```
+- Note: this annotation also has to be checked in other cases, e.g. when watching for the Cluster resource.
+
+## MachinePool API group changed to `cluster.x-k8s.io`
+
+MachinePool is today an experiment, and the API group we originally decided to pick was `exp.cluster.x-k8s.io`. Given that the intent is in the future to move MachinePool to the core API group, we changed the experiment to use `cluster.x-k8s.io` group to avoid future breaking changes.
+
+All InfraMachinePool implementations should be moved to `infrastructure.cluster.x-k8s.io`. See `DockerMachinePool` for an example.
+
+Note that MachinePools are still experimental after this change and should still be feature gated.
+
+## Golangci-lint configuration
+
+There were a lot of new useful linters added to `.golangci.yml`. Of course it's not mandatory to use `golangci-lint` or
+a similar configuration, but it might make sense regardless. Please note there was previously an error in
+the `exclude` configuration which has been fixed in [#4657](https://github.com/kubernetes-sigs/cluster-api/pull/4657). As
+this configuration has been duplicated in a few other providers, it could be that you're also affected.
+
+# test/helpers.NewFakeClientWithScheme has been removed
+
+This function used to create a new fake client with the given scheme for testing,
+and all the objects given as input were initialized with a resource version of "1".
+The behavior of having a resource version in fake client has been fixed in controller-runtime,
+and this function isn't needed anymore.
+
+## Required kustomize changes to remove Kubeadm-rbac-proxy
+
+NB. instructions assumes "Required kustomize changes to have a single manager watching all namespaces and answer to webhook calls"
+should be executed before this changes.
+
+**Changes in the `/config/default` folder:**
+1. Edit `/config/default/kustomization.yaml` and remove the `manager_auth_proxy_patch.yaml` item from the `patchesStrategicMerge` list.
+1. Delete the `/config/default/manager_auth_proxy_patch.yaml` file.
+
+**Changes in the `/config/manager` folder:**
+1. Edit `/config/manager/manager.yaml` and remove the `--metrics-bind-addr=127.0.0.1:8080` arg from the `args` list.
+
+**Changes in the `/config/rbac` folder:**
+1. Edit `/config/rbac/kustomization.yaml` and remove following items from the `resources` list.
+   - `auth_proxy_service.yaml`
+   - `auth_proxy_role.yaml`
+   - `auth_proxy_role_binding.yaml`
+1. Delete the `/config/rbac/auth_proxy_service.yaml` file.
+1. Delete the `/config/rbac/auth_proxy_role.yaml` file.
+1. Delete the `/config/rbac/auth_proxy_role_binding.yaml` file.
+
+**Changes in the `main.go` file:**
+1. Change the default value for the `metrics-bind-addr` from `:8080` to `localhost:8080`
+
+## Required cluster template changes
+
+- `spec.infrastructureTemplate` has been moved to `spec.machineTemplate.infrastructureRef`. Thus, cluster templates which include `KubeadmControlPlane`
+have to be adjusted accordingly.
+- `spec.nodeDrainTimeout` has been moved to `spec.machineTemplate.nodeDrainTimeout`.

+## Running the end-to-end tests locally
+
+Usually the e2e tests are executed by Prow, either pre-submit (on PRs) or periodically on certain branches
+(e.g. the default branch). Those jobs are defined in the kubernetes/test-infra repository in [config/jobs/kubernetes-sigs/cluster-api](https://github.com/kubernetes/test-infra/tree/master/config/jobs/kubernetes-sigs/cluster-api).
+For development and debugging those tests can also be executed locally.
+
+### Prerequisites

+`make docker-build-e2e` will build the images for all providers that will be needed for the e2e tests.
+
+### Test execution via ci-e2e.sh
+
+To run a test locally via the command line, you should look at the Prow Job configuration for the test you want to run and then execute the same commands locally.
+For example to run [pull-cluster-api-e2e-main](https://github.com/kubernetes/test-infra/blob/49ab08a6a2a17377d52a11212e6f1104c3e87bfc/config/jobs/kubernetes-sigs/cluster-api/cluster-api-presubmits-main.yaml#L113-L140)

+provider code changes. If the provider code is changed, run `make docker-build-e2e` to update the images.
+
+### Test execution via IDE
+
+It's also possible to run the tests via an IDE which makes it easier to debug the test code by stepping through the code.
+
+First, we have to make sure all prerequisites are fulfilled, i.e. all required images have been built (this also includes 
+kind images). This can be done by executing the `./scripts/ci-e2e.sh` script.
+
+```bash
+# Notes:
+# * You can cancel the script as soon as it starts the actual test execution via `make -C test/e2e/ run`.
+# * If you want to run other tests (e.g. upgrade tests), make sure all required env variables are set (see the Prow Job config). 
+GINKGO_FOCUS="\[PR-Blocking\]" ./scripts/ci-e2e.sh
+
+# Make sure the cluster-templates have been generated.
+make -C test/e2e cluster-templates
+```
+
+Now, the tests can be run in an IDE. The following describes how this can be done in Intellij IDEA and VS Code. It should work
+roughly the same way in all other IDEs. We assume the `cluster-api` repository has been checked
+out into `/home/user/code/src/sigs.k8s.io/cluster-api`.
+
+#### Intellij 
+
+Create a new run configuration and fill in:
+* Test framework: `gotest`
+* Test kind: `Package`
+* Package path: `sigs.k8s.io/cluster-api/test/e2e`
+* Pattern: `^\QTestE2E\E$`
+* Working directory: `/home/user/code/src/sigs.k8s.io/cluster-api/test/e2e`
+* Environment: `ARTIFACTS=/home/user/code/src/sigs.k8s.io/cluster-api/_artifacts`
+* Program arguments: `-e2e.config=/home/user/code/src/sigs.k8s.io/cluster-api/test/e2e/config/docker.yaml -ginkgo.focus="\[PR-Blocking\]"`
+
+#### VS Code
+
+Add the launch.json file in the .vscode folder in your repo:
+```json
+{
+    "version": "0.2.0",
+    "configurations": [
+        {
+            "name": "Run e2e test",

+            "showGlobalVariables": true
+        }
+    ]
+}
+```
+
+Execute the run configuration with `Debug`.

+### Running specific tests
+
+To run a subset of tests, a combination of either one or both of `GINKGO_FOCUS` and `GINKGO_SKIP` env variables can be set.
+Each of these can be used to match tests, for example:
+- `[PR-Blocking]` => Sanity tests run before each PR merge

 - `ARTIFACTS` to set the folder where test artifact will be stored (default to ${REPO_ROOT}/_artifacts)
 - `SKIP_RESOURCE_CLEANUP` to skip resource cleanup at the end of the test (useful for problem investigation) (default to false)

 [Kubeadm](https://kubernetes.io/docs/reference/setup-tools/kubeadm/kubeadm/) was designed as a focused tool for bootstrapping a best-practices Kubernetes cluster. The core tenet behind the kubeadm project was to create a tool that other installers can leverage and ultimately alleviate the amount of configuration that an individual installer needed to maintain. Since it began, kubeadm has become the underlying bootstrapping tool for several other applications, including Kubespray, Minikube, kind, etc.

 * How can I consistently provision machines, load balancers, VPC, etc., across multiple infrastructure providers and locations?
 * How can I automate cluster lifecycle management, including things like upgrades and cluster deletion?

 ## Generating a Kubeconfig with your own CA
 
 1. Create a new Certificate Signing Request (CSR) for the `system:masters` Kubernetes role, or specify any other role under CN.
-```bash
-openssl req  -subj "/CN=system:masters" -new -newkey rsa:2048 -nodes -out admin.csr -keyout admin.key  -out admin.csr

+
+   ```bash
+   openssl req  -subj "/CN=system:masters" -new -newkey rsa:2048 -nodes -out admin.csr -keyout admin.key  -out admin.csr
+   ```
+
 2. Sign the CSR using the *[cluster-name]-ca* key:
-```bash
-openssl x509 -req -in admin.csr -CA tls.crt -CAkey tls.key -CAcreateserial -out admin.crt -days 5 -sha256
-```
+
+   ```bash
+   openssl x509 -req -in admin.csr -CA tls.crt -CAkey tls.key -CAcreateserial -out admin.crt -days 5 -sha256
+   ```
+
 3. Update your kubeconfig with the sign key:
-```bash
-kubectl config set-credentials cluster-admin --client-certificate=admin.crt --client-key=admin.key --embed-certs=true
-```
+
+   ```bash
+   kubectl config set-credentials cluster-admin --client-certificate=admin.crt --client-key=admin.key --embed-certs=true

-# Changing Infrastructure Machine Templates
-
-Several different components of Cluster API leverage _infrastructure machine templates_, 
-including `KubeadmControlPlane`, `MachineDeployment`, and `MachineSet`. These 
-`MachineTemplate` resources should be immutable, unless the infrastructure provider 
-documentation indicates otherwise for certain fields (see below for more details).
-
-The correct process for modifying an infrastructure machine template is as follows:
-
-1. Duplicate an existing template.
-    Users can use `kubectl get <MachineTemplateType> <name> -o yaml > file.yaml` 
-    to retrieve a template configuration from a running cluster to serve as a starting 
-    point.
-2. Update the desired fields.
-    Fields that might need to be modified could include the SSH key, the AWS instance 
-    type, or the Azure VM size. Refer to the provider-specific documentation 
-    for more details on the specific fields that each provider requires or accepts.
-3. Give the newly-modified template a new name by modifying the `metadata.name` field 
-    (or by using `metadata.generateName`).
-4. Create the new infrastructure machine template on the API server using `kubectl`. 
-    (If the template was initially created using the command in step 1, be sure to clear 
-    out any extraneous metadata, including the `resourceVersion` field, before trying to 
-    send it to the API server.)
-
-Once the new infrastructure machine template has been persisted, users may modify 
-the object that was referencing the infrastructure machine template. For example, 
-to modify the infrastructure machine template for the `KubeadmControlPlane` object, 
-users would modify the `spec.infrastructureTemplate.name` field. For a `MachineDeployment` 
-or `MachineSet`, users would need to modify the `spec.template.spec.infrastructureRef.name` 
-field. In all cases, the `name` field should be updated to point to the newly-modified 
-infrastructure machine template. This will trigger a rolling update. (This same process 
-is described in the documentation for [upgrading the underlying machine image for 
-KubeadmControlPlane](./kubeadm-control-plane.md) in the "How to upgrade the underlying 
-machine image" section.)
-
-Some infrastructure providers _may_, at their discretion, choose to support in-place 
-modifications of certain infrastructure machine template fields. This may be useful 
-if an infrastructure provider is able to make changes to running instances/machines, 
-such as updating allocated memory or CPU capacity. In such cases, however, Cluster 
-API **will not** trigger a rolling update.

+# Updating Machine Infrastructure and Bootstrap Templates
+
+## Updating Infrastructure Machine Templates
+
+Several different components of Cluster API leverage _infrastructure machine templates_,
+including `KubeadmControlPlane`, `MachineDeployment`, and `MachineSet`. These
+`MachineTemplate` resources should be immutable, unless the infrastructure provider
+documentation indicates otherwise for certain fields (see below for more details).
+
+The correct process for modifying an infrastructure machine template is as follows:
+
+1. Duplicate an existing template.
+    Users can use `kubectl get <MachineTemplateType> <name> -o yaml > file.yaml`
+    to retrieve a template configuration from a running cluster to serve as a starting
+    point.
+2. Update the desired fields.
+    Fields that might need to be modified could include the SSH key, the AWS instance
+    type, or the Azure VM size. Refer to the provider-specific documentation
+    for more details on the specific fields that each provider requires or accepts.
+3. Give the newly-modified template a new name by modifying the `metadata.name` field
+    (or by using `metadata.generateName`).
+4. Create the new infrastructure machine template on the API server using `kubectl`.
+    (If the template was initially created using the command in step 1, be sure to clear
+    out any extraneous metadata, including the `resourceVersion` field, before trying to
+    send it to the API server.)
+
+Once the new infrastructure machine template has been persisted, users may modify
+the object that was referencing the infrastructure machine template. For example,
+to modify the infrastructure machine template for the `KubeadmControlPlane` object,
+users would modify the `spec.infrastructureTemplate.name` field. For a `MachineDeployment`
+or `MachineSet`, users would need to modify the `spec.template.spec.infrastructureRef.name`
+field. In all cases, the `name` field should be updated to point to the newly-modified
+infrastructure machine template. This will trigger a rolling update. (This same process
+is described in the documentation for [upgrading the underlying machine image for
+KubeadmControlPlane](./kubeadm-control-plane.md) in the "How to upgrade the underlying
+machine image" section.)
+
+Some infrastructure providers _may_, at their discretion, choose to support in-place
+modifications of certain infrastructure machine template fields. This may be useful
+if an infrastructure provider is able to make changes to running instances/machines,
+such as updating allocated memory or CPU capacity. In such cases, however, Cluster
+API **will not** trigger a rolling update.
+
+## Updating Bootstrap Templates
+
+Several different components of Cluster API leverage _bootstrap templates_,
+including `MachineDeployment`, and `MachineSet`. When used in `MachineDeployment` or 
+`MachineSet` changes to those templates do not trigger rollouts of already existing `Machines`.
+New `Machines` are created based on the current version of the bootstrap template.
+
+The correct process for modifying a bootstrap template is as follows:
+
+1. Duplicate an existing template.
+   Users can use `kubectl get <BootstrapTemplateType> <name> -o yaml > file.yaml`
+   to retrieve a template configuration from a running cluster to serve as a starting
+   point.
+2. Update the desired fields.
+3. Give the newly-modified template a new name by modifying the `metadata.name` field
+   (or by using `metadata.generateName`).
+4. Create the new bootstrap template on the API server using `kubectl`.
+   (If the template was initially created using the command in step 1, be sure to clear
+   out any extraneous metadata, including the `resourceVersion` field, before trying to
+   send it to the API server.)
+
+Once the new bootstrap template has been persisted, users may modify
+the object that was referencing the bootstrap template. For example,
+to modify the bootstrap template for the `MachineDeployment` object,
+users would modify the `spec.template.spec.bootstrap.configRef.name` field.
+The `name` field should be updated to point to the newly-modified
+bootstrap template. This will trigger a rolling update.

-### Prerequisites
-
-There are a few preliminary steps needed to be able to run `clusterctl init` on a [management cluster] with `v1alpha2` [components] installed.
-
-#### Delete the cabpk-system namespace
-
-<aside class="note warning">
-
-<h1>Warning</h1>
-
-Please proceed with caution and ensure you do not have any additional components deployed on the namespace.
-
-</aside>
-
-Delete the `cabpk-system` namespace by running:
-
-```bash
-kubectl delete namespace cabpk-system
-```
-
-#### Delete the core and infrastructure provider controller-manager deployments
-
-Delete the `capi-controller-manager` deployment from the `capi-system` namespace:
-
-```bash
-kubectl delete deployment capi-controller-manager -n capi-system
-```
-
-Depending on your infrastructure provider, delete the controller-manager deployment.
-
-For example, if you are using the [AWS provider], delete the `capa-controller-manager` deployment from the `capa-system` namespace:
-
-```bash
-kubectl delete deployment capa-controller-manager -n capa-system
-```
-
-#### Optional: Ensure preserveUnknownFields is set to 'false' for the infrastructure provider CRDs Spec
-This should be the case for all infrastructure providers using conversion webhooks to allow upgrading from `v1alpha2` to
-`v1alpha3`.
-
-This can verified by running `kubectl get crd <crd name>.infrastructure.cluster.x-k8s.io -o yaml` for all the
-infrastructure provider CRDs.
-
-### Upgrade Cluster API components using clusterctl
-
-Run [clusterctl init] with the relevant infrastructure flag. For the [AWS provider] you would run:
-
-```bash
-clusterctl init --infrastructure aws
-```
-
-You should now be able to manage your resources using the `v1alpha3` version of the Cluster API components.
-
-### Adopting existing machines into KubeadmControlPlane management
-
-<aside class="note warning">
-
-<h1> Important </h1>
-
-You must be running at least Cluster API 0.3.7 for adoption to be successful.
-
-</aside>
-
-If your cluster has existing machines labeled with `cluster.x-k8s.io/control-plane`, you may opt in to management of those machines by
-creating a new KubeadmControlPlane object and updating the associated Cluster object's `controlPlaneRef` like so:
-
-```
----
-apiVersion: "cluster.x-k8s.io/v1alpha3"
-kind: Cluster
-...
-spec:
-  controlPlaneRef:
-    apiVersion: controlplane.cluster.x-k8s.io/v1alpha3
-    kind: KubeadmControlPlane
-    name: controlplane
-    namespace: default
-...
-```
-
-Caveats:
-
-* The KCP controller will refuse to adopt any control plane Machines not bootstrapped with the kubeadm bootstrapper.
-* The KCP controller may immediately begin upgrading Machines post-adoption if they're out of date.
-* The KCP controller attempts to behave intelligently when adopting existing Machines, but because the bootstrapping process sets various fields in the KubeadmConfig of a machine it's not always obvious the original user-supplied `KubeadmConfig` would have been for that machine. The controller attempts to guess this intent to not replace Machines unnecessarily, so if it guesses wrongly, the consequence is that the KCP controller will effect an "upgrade" to its current config.
-* If the cluster's PKI materials were generated by an initial KubeadmConfig reconcile, they'll be owned by the KubeadmConfig bound to that machine. The adoption process re-parents these resources to the KCP so they're not lost during an upgrade, but deleting the KCP post-adoption will destroy those materials.
-* The `ClusterConfiguration`  is only partially reconciled with their ConfigMaps the workload cluster, and `kubeadm` considers the ConfigMap authoritative. Fields which are reconciled include:
-    * `kubeadmConfigSpec.clusterConfiguration.etcd.local.imageRepository`
-    * `kubeadmConfigSpec.clusterConfiguration.etcd.local.imageTag`
-    * `kubeadmConfigSpec.clusterConfiguration.dns.imageRepository`
-    * `kubeadmConfigSpec.clusterConfiguration.dns.imageTag`
-    * Further information can be found in [issue 2083][issue2083]
+You should now be able to manage your resources using the `v1alpha4` version of the Cluster API components.

 Some infrastructure providers, such as [AWS](https://github.com/kubernetes-sigs/cluster-api-provider-aws), require
 that if a specific machine image is specified, it has to match the Kubernetes version specified in the
 `KubeadmControlPlane` spec. In order to only trigger a single upgrade, the new `MachineTemplate` should be created first
 and then both the `Version` and `InfrastructureTemplate` should be modified in a single transaction.
 
+#### How to schedule a machine rollout
+
+A `KubeadmControlPlane` resource has a field `RolloutAfter` that can be set to a timestamp
+(RFC-3339) after which a rollout should be triggered regardless of whether there were any changes
+to the `KubeadmControlPlane.Spec` or not. This would roll out replacement control plane nodes
+which can be useful e.g. to perform certificate rotation, reflect changes to machine templates,
+move to new machines, etc.
+
+Note that this field can only be used for triggering a rollout, not for delaying one. Specifically,
+a rollout can also happen before the time specified in `RolloutAfter` if any changes are made to
+the spec before that time.
+
+To do the same for machines managed by a `MachineDeployment` it's enough to make an arbitrary
+change to its `Spec.Template`, one common approach is to run:
+
+``` shell
+clusterctl alpha rollout restart machinedeployment/my-md-0
+```
+
+This will modify the template by setting an `cluster.x-k8s.io/restartedAt` annotation which will
+trigger a rollout.

+# Using Kustomize with Workload Cluster Manifests
+
+Although the `clusterctl generate cluster` command exposes a number of different configuration values
+for customizing workload cluster YAML manifests, some users may need additional flexibility above
+and beyond what `clusterctl generate cluster` or the example "flavor" templates that some CAPI providers
+supply (as an example, see [these flavor templates](https://github.com/kubernetes-sigs/cluster-api-provider-azure/tree/main/templates/flavors)
+for the Cluster API Provider for Azure). In the future, a [templating solution](https://github.com/kubernetes-sigs/cluster-api/issues/3252)
+may be integrated into `clusterctl` to help address this need, but in the meantime users can use
+`kustomize` as a solution to this need.
+
+This document provides a few examples of using `kustomize` with Cluster API. All of these examples
+assume that you are using a directory structure that looks something like this:
+
+```
+.
+├── base
+│   ├── base.yaml
+│   └── kustomization.yaml
+└── overlays
+    ├── custom-ami
+    │   ├── custom-ami.json
+    │   └── kustomization.yaml
+    └── mhc
+        ├── kustomization.yaml
+        └── workload-mhc.yaml
+```
+
+In the overlay directories, the "base" (unmodified) Cluster API configuration (perhaps generated using
+`clusterctl generate cluster`) would be referenced as a resource in `kustomization.yaml` using `../../base`.
+
+## Example: Using Kustomize to Specify Custom Images
+
+Users can use `kustomize` to specify custom OS images for Cluster API nodes. Using the Cluster API
+Provider for AWS (CAPA) as an example, the following `kustomization.yaml` would leverage a JSON 6902 patch
+to modify the AMI for nodes in a workload cluster:
+
+```yaml
+---
+apiVersion: kustomize.config.k8s.io/v1beta1
+kind: Kustomization
+resources:
+  - ../../base
+patchesJson6902:
+  - path: custom-ami.json
+    target:
+      group: infrastructure.cluster.x-k8s.io
+      kind: AWSMachineTemplate
+      name: ".*"
+      version: v1alpha3
+```
+
+The referenced JSON 6902 patch in `custom-ami.json` would look something like this:
+
+```json
+[
+    { "op": "add", "path": "/spec/template/spec/ami", "value": "ami-042db61632f72f145"}
+]
+```
+
+This configuration assumes that the workload cluster _only_ uses MachineDeployments. Since
+MachineDeployments and the KubeadmControlPlane both leverage AWSMachineTemplates, this `kustomize`
+configuration would catch all nodes in the workload cluster.
+
+## Example: Adding a MachineHealthCheck for a Workload Cluster
+
+Users could also use `kustomize` to combine additional resources, like a MachineHealthCheck (MHC), with the
+base Cluster API manifest. In an overlay directory, specify the following in `kustomization.yaml`:
+
+```yaml
+---
+apiVersion: kustomize.config.k8s.io/v1beta1
+kind: Kustomization
+resources:
+  - ../../base
+  - workload-mhc.yaml
+```
+
+The content of the `workload-mhc.yaml` file would be the definition of a standard MHC:
+
+```yaml
+apiVersion: cluster.x-k8s.io/v1alpha3
+kind: MachineHealthCheck
+metadata:
+  name: md-0-mhc
+spec:
+  clusterName: test
+  # maxUnhealthy: 40%
+  nodeStartupTimeout: 10m
+  selector:
+    matchLabels:
+      cluster.x-k8s.io/deployment-name: md-0
+  unhealthyConditions:
+  - type: Ready
+    status: Unknown
+    timeout: 300s
+  - type: Ready
+    status: "False"
+    timeout: 300s
+```
+
+You would want to ensure the `clusterName` field in the MachineHealthCheck manifest appropriately
+matches the name of the workload cluster, taking into account any transformations you may have specified
+in `kustomization.yaml` (like the use of "namePrefix" or "nameSuffix").
+
+Running `kustomize build .` with this configuration would append the MHC to the base
+Cluster API manifest, thus creating the MHC at the same time as the workload cluster.
+
+## Modifying Names
+
+The `kustomize` "namePrefix" and "nameSuffix" transformers are not currently "Cluster API aware."
+Although it is possible to use these transformers with Cluster API manifests, doing so requires separate
+patches for Clusters versus infrastructure-specific equivalents (like an AzureCluster or a vSphereCluster).
+This can significantly increase the complexity of using `kustomize` for this use case.
+
+Modifying the transformer configurations for `kustomize` can make it more effective with Cluster API.
+For example, changes to the `nameReference` transformer in `kustomize` will enable `kustomize` to know
+about the references between Cluster API objects in a manifest. See
+[here](https://github.com/kubernetes-sigs/kustomize/tree/master/examples/transformerconfigs) for more
+information on transformer configurations.
+
+Add the following content to the `namereference.yaml` transformer configuration:
+
+```yaml
+- kind: Cluster
+  group: cluster.x-k8s.io
+  version: v1alpha3
+  fieldSpecs:
+  - path: spec/clusterName
+    kind: MachineDeployment
+  - path: spec/template/spec/clusterName
+    kind: MachineDeployment
+
+- kind: AWSCluster
+  group: infrastructure.cluster.x-k8s.io
+  version: v1alpha3
+  fieldSpecs:
+  - path: spec/infrastructureRef/name
+    kind: Cluster
+
+- kind: KubeadmControlPlane
+  group: controlplane.cluster.x-k8s.io
+  version: v1alpha3
+  fieldSpecs:
+  - path: spec/controlPlaneRef/name
+    kind: Cluster
+
+- kind: AWSMachine
+  group: infrastructure.cluster.x-k8s.io
+  version: v1alpha3
+  fieldSpecs:
+  - path: spec/infrastructureRef/name
+    kind: Machine
+
+- kind: KubeadmConfig
+  group: bootstrap.cluster.x-k8s.io
+  version: v1alpha3
+  fieldSpecs:
+  - path: spec/bootstrap/configRef/name
+    kind: Machine
+
+- kind: AWSMachineTemplate
+  group: infrastructure.cluster.x-k8s.io
+  version: v1alpha3
+  fieldSpecs:
+  - path: spec/template/spec/infrastructureRef/name
+    kind: MachineDeployment
+  - path: spec/infrastructureTemplate/name
+    kind: KubeadmControlPlane
+
+- kind: KubeadmConfigTemplate
+  group: bootstrap.cluster.x-k8s.io
+  version: v1alpha3
+  fieldSpecs:
+  - path: spec/template/spec/bootstrap/configRef/name
+    kind: MachineDeployment
+```
+
+Including this custom configuration in a `kustomization.yaml` would then enable the use of simple
+"namePrefix" and/or "nameSuffix" directives, like this:
+
+```yaml
+---
+apiVersion: kustomize.config.k8s.io/v1beta1
+kind: Kustomization
+resources:
+  - ../../base
+configurations:
+  - namereference.yaml
+namePrefix: "blue-"
+nameSuffix: "-dev"
+```
+
+Running `kustomize build. ` with this configuration would modify the name of all the Cluster API
+objects _and_ the associated referenced objects, adding "blue-" at the beginning and appending "-dev"
+at the end.

 # Troubleshooting
 
+## Node bootstrap failures when using CABPK with cloud-init
+
+Failures during Node bootstrapping can have a lot of different causes. For example, Cluster API resources might be 
+misconfigured or there might be problems with the network. The following steps describe how bootstrap failures can 
+be troubleshooted systematically.
+
+1. Access the Node via ssh.
+1. Take a look at cloud-init logs via `less /var/log/cloud-init-output.log` or `journalctl -u cloud-init --since "1 day ago"`.
+   (Note: cloud-init persists logs of the commands it executes (like kubeadm) only after they have returned.)
+1. It might also be helpful to take a look at `journalctl --since "1 day ago"`.
+1. If you see that kubeadm times out waiting for the static Pods to come up, take a look at:
+   1. containerd: `crictl ps -a`, `crictl logs`, `journalctl -u containerd`
+   1. Kubelet: `journalctl -u kubelet --since "1 day ago"`
+      (Note: it might be helpful to increase the Kubelet log level by e.g. setting `--v=8` via 
+      `systemctl edit --full kubelet && systemctl restart kubelet`)
+1. If Node bootstrapping consistently fails and the kubeadm logs are not verbose enough, the `kubeadm` verbosity 
+   can be increased via `KubeadmConfigSpec.Verbosity`.
+

+## Cluster API with Docker
+
+When provisioning workload clusters using Cluster API with Docker infrastructure,
+provisioning might be stuck: 
+ 
+1. if there are stopped containers on your machine from previous runs. Clean unused containers with [docker rm -f ](https://docs.docker.com/engine/reference/commandline/rm/). 
+
+2. if the docker space on your disk is being exhausted 
+    * Run [docker system df](https://docs.docker.com/engine/reference/commandline/system_df/) to inspect the disk space consumed by Docker resources.
+    * Run [docker system prune --volumes](https://docs.docker.com/engine/reference/commandline/system_prune/) to prune dangling images, containers, volumes and networks.

This should include at least the state of etcd and information about which replicas are currently healthy or not. For the default implementation, health attributes based on artifacts kubeadm installs on the cluster may also be of interest to cluster operators.

With `MaxSurge` field user is able to delete old machine first during upgrade.

+##### Rolling update strategy
+
+Currently KubeadmControlPlane supports only one rollout strategy type the `RollingUpdateStrategyType`. Rolling upgrade strategy's behavior can be modified by using `MaxSurge` field. The field values can be an absolute number 0 or 1.
+
+When `MaxSurge` is set to 1 the rollout algorithm is as follows:
 
-- The rollout algorithm is the following:
   - Find Machines that have an outdated spec
   - If there is a machine requiring rollout
     - Scale up control plane creating a machine with the new spec
     - Scale down control plane by removing one of the machine that needs rollout (the oldest out-of date machine in the failure domain that has the most control-plane machines on it)
 
-- In order to determine if a Machine to be rolled out, KCP implements the following:
-    - The infrastructureRef link used by each machine at creation time is stored in annotations at machine level.
-    - The kubeadmConfigSpec used by each machine at creation time is stored in annotations at machine level.
-        - If the annotation is not present (machine is either old or adopted), we won't roll out on any possible changes made in KCP's ClusterConfiguration given that we don't have enough information to make a decision.
-           Users should use KCP.Spec.UpgradeAfter field to force a rollout in this case.
+When `MaxSurge` is set to 0 the rollout algorithm is as follows:
 
-- The controller should tolerate the manual or automatic removal of a replica during the upgrade process. A replica that fails during the upgrade may block the completion of the upgrade. Removal or other remedial action may be necessary to allow the upgrade to complete.
+  - KubeadmControlPlane verifies that control plane replica count is >= 3
+  - Find Machines that have an outdated spec and scale down the control plane by removing the oldest out-of-date machine.
+  - Scale up control plane by creating a new machine with the updated spec
+
+> NOTE: Setting `MaxSurge` to 0 could be use in resource constrained environment like bare-metal, OpenStack or vSphere resource pools, etc when there is no capacity to Scale up the control plane.
 
 ###### Constraints and Assumptions
 
-* A stable endpoint (provided by DNS or IP) for the API server will be required in order to allow for machines to maintain a connection to control plane machines as they are swapped out during upgrades. This proposal is agnostic to how this is achieved, and is being tracked in https://github.com/kubernetes-sigs/cluster-api/issues/1687. The control plane controller will use the presence of the apiEndpoints status field of the cluster object to  determine whether or not to proceed. This behaviour is currently implicit in the implementations for cloud providers that provider a load balancer construct.

+4. Machine controller ensures the interruptible label is always present on the Node if InfraMachine.status.interruptible is true.

+## Glossary
+
+Refer to the [Cluster API Book Glossary](https://cluster-api.sigs.k8s.io/reference/glossary.html).
+
+## Summary
+
+This proposal is for the support of Windows [OS](https://cluster-api.sigs.k8s.io/reference/glossary.html#operating-system) worker nodes in Cluster API and [infrastructure providers](https://cluster-api.sigs.k8s.io/reference/glossary.html#infrastructure-provider) that wish to support 
+Windows. Cluster API will support Windows by using kubeadm to add Windows nodes to a [workload cluster](https://cluster-api.sigs.k8s.io/reference/glossary.html#workload-cluster). 
+
+Windows support has been stable in Kubernetes since 1.14 and is supported in clusters that run Linux for the
+Control Plane.  The Worker nodes can be any combination of Windows or Linux. 
+
+Windows node support has some unique challenges because of the current limitations of Windows Containers. 
+Windows containers do not support privileged operations which means that configuration and access to the host
+machine must be done at provisioning time.  
+
+An example of this limitation is how kube-proxy gets configured on Windows nodes. Kube-proxy typically runs as a 
+Windows service on the host machine and it cannot be deployed as a DaemonSet as it is on Linux.  
+To address this limitation the community has built tools such as the [CSI-Proxy](https://github.com/kubernetes-csi/csi-proxy), which is a CSI driver specific proxy. 
+This proposal will address how to approach the configuration of components that are typically deployed as 
+daemon sets when bootstrapping Windows nodes in CAPI.
+
+## Motivation
+
+Kubernetes has supported Windows workloads since the release of Windows support in Kubernetes 1.14. The 
+motivation of this proposal is to enable Cluster API users to deploy Windows as part of a mixed OS cluster 
+via the Cluster API automation built for platform operators.  This will enable cluster operators to define 
+Windows machines in the same consistent and repeatable fashion.
+
+### Goals
+
+- Enable the creation and management of Windows worker nodes on workload clusters by adding support via the Kubeadm bootstrap provider and infrastructure providers
+- Provide community guidance and scripts for building base images for Windows nodes
+- Re-use of the existing Cluster API Bootstrap Provider Kubeadm and other tools where appropriate
+
+### Non-Goals/Future Work
+
+- Provide a way to run [control plane](https://cluster-api.sigs.k8s.io/reference/glossary.html#control-plane) nodes as Windows
+- Support for Windows versions outside of the Kubernetes support versions
+- Support for Windows nodes on the [management](https://cluster-api.sigs.k8s.io/reference/glossary.html#management-cluster) or [bootstrap clusters](https://cluster-api.sigs.k8s.io/reference/glossary.html#bootstrap-cluster)
+- Provide a way to configure Windows nodes with non-Kubeadm based bootstrap providers
+
+## Proposal
+
+### Cluster API Bootstrap Provider Kubeadm
+
+#### cloud-init and cloudbase-init
+
+For Linux, when using the Kubeadm bootstrap provider, the bootstrap script is provided to the infrastructure provider as a cloud-init script. 
+The infrastructure provider is responsible for putting the cloud-init script in the right location. 
+When the VM is booted, the cloud-init script runs automatically. 
+
+Cloud-init does not have Windows support. An alternative product is [cloudbase-init](https://github.com/cloudbase/cloudbase-init). 
+Cloudbase-init functions in the same way as cloud-init and can consume cloud-init scripts as provided by the Cluster API Bootstrap Provider Kubeadm.  
+By using cloudbase-init, Windows can leverage the existing solutions and stay up to date with the latest changes in CABPK.  Refer to the [cloudbase-init documentation](https://cloudbase-init.readthedocs.io/en/latest/intro.html) for features that are supported.
+
+#### Image Creation
+
+Using cloudbase-init requires the creation of an image with the tooling installed on it since it is not 
+provided out of the box by any cloud providers.  We'll provide packer scripts as part of 
+the [image-builder project](https://github.com/kubernetes-sigs/image-builder) that pre-installs 
+`cloudbase-init`.  It is important to note that while scripts can be provided to build an image, all images 
+built need to adhere to [Windows licensing requirements](https://www.microsoft.com/en-us/licensing/product-licensing/windows-server).
+
+There is prior art for building Windows base images. For example, AKS-Engine has an example implementation for using packer and scripts to do image configuration: https://github.com/Azure/aks-engine/blob/master/vhd/packer/windows-vhd-builder.json.  
+Another example is the the [sig-windows-tools](https://github.com/kubernetes-sigs/sig-windows-tools) which provide scripts for image configuration when using Kubeadm.
+
+Although the Linux implementation in image-builder uses Ansible for configuration, Windows isn't going to share
+the same configuration because [Ansible](https://docs.ansible.com/ansible/latest/user_guide/windows.html) requires [Windows specific modules](https://docs.ansible.com/ansible/latest/modules/list_of_windows_modules.html) to do the configuration. 
+
+#### Kubelet and other component configuration
+
+Due to the lack of privileged containers in Windows, a combination of `PreKubeadmCommands`/`PostKubeadmCommands` 
+scripts and wins.exe can be used to configure the nodes. Wins.exe is currently provided as a way to bootstrap nodes along with kubeadm in the [Kubernetes documentation for adding Windows nodes](https://kubernetes.io/docs/tasks/administer-cluster/kubeadm/adding-windows-nodes/).  
+The components from the [preparenode script](https://kubernetes.io/docs/tasks/administer-cluster/kubeadm/adding-windows-nodes/#joining-a-windows-worker-node) can be used during image creation.
+
+In the future, when support for [Privileged Containers for Windows containers](https://github.com/kubernetes/enhancements/issues/1981) is merged, we might be able to revisit this proposal 
+and use privileged containers in place of wins.exe enabled containers. 
+
+Each infrastructure providers must provide their own `PreKubeadmCommands`/`PostKubeadmCommands` scripts that
+are required for additional configuration for the node. During planning for Beta we will be able to identify
+common overlapping features that can be added into the the base images in image-builder and for re-use 
+
+#### netbios names
+
+Cluster API currently generates the machine deployment name which can result in long machine names.  This was a was concern for Netbios on Windows which requires Windows computer names to be 15 characters or fewer (https://support.microsoft.com/en-us/help/909264/naming-conventions-in-active-directory-for-computers-domains-sites-and). 
+Attempting to set a hostname with more than 15 characters on a windows machine will result in only the first 15 being used.
+
+The conclusion of the [issue](https://github.com/kubernetes-sigs/cluster-api/issues/2217) was NETBIOS name resolution is mostly unused today and is not required to join an AD domain since Windows 2000. If DNS is properly configured then the long host names generated by Cluster API will be usable.  
+
+### Infrastructure provider implementation
+
+By leveraging cloudbase-init, an infrastructure provider implementation will require only a few changes which include:
+
+- Make changes to their provider api to enable Windows OS infra machines ([example](https://github.com/ionutbalutoiu/cluster-api-provider-azure/commit/9c8daedac75959b141fec7ea909c2c1fd0bd484b))
+- Ensuring cloudbase-init is configured properly to read UserData which will contain the cloud-init script.  Users must configure 
+[cloudbase-init with a metadata service](https://cloudbase-init.readthedocs.io/en/latest/services.html#configuring-available-services) that has support for [UserData](https://cloudbase-init.readthedocs.io/en/latest/userdata.html) ([example](https://cloudbase-init.readthedocs.io/en/latest/tutorial.html#configuration-file)).
+
+From the infrastructure provider perspective, there are no known required changes to the CAPI API to support Windows
+nodes at this time. If during alpha we identify changes we will open issues pertaining to the changes required.
+
+### User Stories
+
+#### As an operator, I would like to create Windows OS worker nodes with the CAPI API.
+
+#### As an operator, I would like to manage Windows OS worker nodes with the CAPI API.
+
+### Implementation Details/Notes/Constraints
+
+Due to the lack of privileged containers in Windows there are two options for configuring the components such as 
+kube-proxy, kubelet.  The above solution using wins is preferred because it makes the move to privileged containers 
+straightforward as a drop and replace. 
+
+While this is the best choice for the alpha and the community direction there are some infrastructure providers that may 
+not be able to use wins due to signing or security concerns since wins allows the execution of any arbitrary command on 
+the host. Pre/post commands can be used as an alternative with additional scripts cached on the image that enable the configuration.
+
+#### Signing of the components.  
+
+Some infrastructure providers will require any scripts and binaries are signed before deployment.  
+This will be managed by providing the ability to provide url's to override external scripts and binaries 
+during the image building process. An example of how this is could be accomplished is in the Linux 
+implementation is the [containerd_url](https://github.com/kubernetes-sigs/image-builder/blob/58a08a1a8241356bab4afb1c6d8d2fbb8ef54bcf/images/capi/packer/config/ansible-args.json).  In this case, the 
+`containerd_url` could point to a location that would contain a packaged with signed binaries from the infrastructure provider.

+
+### Security Model
+
+Wins.exe is currently the [recommended way to use kubeadm](https://kubernetes.io/docs/tasks/administer-cluster/kubeadm/adding-windows-nodes/).  
+Limiting access to the named pipes that are required is one way to mitigate access.  Wins is currently 
+required during and after provisioning for running kube-proxy and the CNI daemonset.  
+
+The security model for Privileged containers is still being discussed in KEP and is still early.  The security concerns for Privileged containers will be addresses in the Beta phase of this proposal after the Privileged containers KEP progresses.
+
+Kubeadm bootstrap token should be able to use multi-part mime documents for cloudbase-init as done for [Linux in CAPA](https://github.com/kubernetes-sigs/cluster-api-provider-aws/blob/28d01d064cc2e5b0286ae23b3be7203f18b00447/controllers/awsmachine_controller.go#L601). 
+This will require an update to Cloudbase-init which does support [mutli-part mime documents](https://cloudbase-init.readthedocs.io/en/latest/userdata.html#multi-part-content) but is missing the [boothook](https://cloudinit.readthedocs.io/en/latest/topics/format.html?highlight=boothook#cloud-boothook) functionality.  
+Support for cloudhooks can be added to cloudbase-init to meet the AWS provider requirement that 
+would bring parity to Linux implementation during the Beta phase.
+
+There is [no known requirement](https://github.com/kubernetes-sigs/cluster-api/issues/2218) for managing the Admin
+Kubeconfig or domain passwords in the Windows configuration. Domain passwords should be managed outside the scope of 
+CAPI and only Kubeadm bootstrap tokens, which have limited lifetime, should be used for the joining the Windows nodes to the cluster. 
+The joining of Windows nodes to a Domain Controller can be accomplished through pre/post kubeadm commands.  Future support could be 
+added via a separate controller that supports composable bootstrapping which is outside of the scope of this CAEP.  Refer 
+to issue [#3761](https://github.com/kubernetes-sigs/cluster-api/issues/3761) for more details.
+
+### Risks and Mitigations
+
+- Privileged containers are not implemented.
+  - There is an active discussion and [KEP](https://docs.google.com/document/d/12EUtMdWFxhTCfFrqhlBGWV70MkZZPOgxw0X-LTR0VAo/edit#) in place.  At the Beta stage the community can do a checkpoint to determine if the solution fits user needs
+- Cloudbase-init is a third party dependency
+  - This project is under Apache 2.0 License : https://github.com/cloudbase/cloudbase-init which is cleared under the CNCF Allow list: https://github.com/cncf/foundation/blob/master/allowed-third-party-license-policy.md
+- Windows image Distribution
+  - Infrastructure providers can provide the ability to use user provided images and images provided by image-promoter are recommended for testing and demonstration purposes. It is recommended the user creates their own image. 
+  - Users using the image scripts must ensure they are following [Windows licensing requirements](https://www.microsoft.com/en-us/licensing/product-licensing/windows-server)
+- Wins.exe is a third party dependency
+  - The project is under the Apache 2.0 License
+
+## Alternatives
+
+1. An alternative to using wins.exe and DaemonSets to do the configuration to download and configure components as services 
+   using the kubeadm pre/post commands. This would require the infrastructure providers to have the ability to pass 
+   configuration through the use of these commands which is already done today. During the Alpha phase with the pre/post 
+   scripts being developed by individual infra providers this will not be an issue.  With the move to Windows privileged
+   containers in Beta, this becomes a non issue as wins will no longer be required.
+
+1. Create a separate bootstrap provider for Windows.  This would require re-implementing a lot of the logic that is 
+   already in CABPK.  
+   When bugs are fixed or changes in behavior occur, Windows would risk being out of sync with the Linux implementation.
+
+1. Modified CABPK provider to have a different output format than cloud-init for Windows nodes.   With Cloudbase-init 
+   there are no requirements to change CABPK which makes the adaption for Windows straightforward. If we were to adapt 
+   the output format of CABPK there is a potential for introduction of bugs and variation in the logic that would be 
+   created for Windows nodes.  This would cause the Windows implementation to differ from others which could lead to 
+   confusion when debugging differences.
+
+## Upgrade Strategy
+
+Nodes that use this pattern will require the infrastructure to be immutable as specified by CAPI documentation.
+
+## Additional Details
+
+### Test Plan [optional]
+
+**Note:** *Section not required until targeted at a release.*
+
+There are no changes to CAPI core proposed at this time. End to end tests in CAPI test suit use [Kind](https://kind.sigs.k8s.io/) and
+Windows does not support Docker in Docker so end to end test can not be added for Windows specific behavior.
+If changes are required during development unit tests will be required.  
+
+For infrastructure providers the testing plan is left up to each infrastructure provider. It is recommended to leverage 
+the existing upstream Kubernetes Windows tests to show that Windows nodes are operating effectively. 
+
+### Graduation Criteria [optional]
+
+**Note:** *Section not required until targeted at a release.*
+
+#### Alpha
+- `PreKubeadmCommands`/`PostKubeadmCommands` command scripts are created per infrastructure provider if required
+- Initially implemented with wins.exe
+- Windows Packer scripts to create image with cloudbase-init added to the image builder scripts
+
+#### Beta
+- Pre/Post commands moved to bootstrap provider if identified as re-usable
+- Adopt privileged containers (dependant on Privileged containers KEP)
+- kubeadm bootstrap token can be kept secret via multi-part mime documents for cloudbase-init. 
+
+#### Stable
+Use of privileged containers. 
+
+### Version Skew Strategy 
+
+The version of support for the Windows operating system is outside the scope of cluster creation.  Please refer 
+to the Kubernetes Windows documentation for the latest version skew support, features, and functionality.

+## Glossary
+
+The lexicon used in this document is described in more detail
+[here](https://github.com/kubernetes-sigs/cluster-api/blob/master/docs/book/src/reference/glossary.md).
+Any discrepancies should be rectified in the main Cluster API glossary.
+
+## Summary
+
+The clusterctl CLI currently handles the lifecycle of Cluster API
+providers installed in a management cluster. It provides a great Day 0 and Day
+1 experience in getting CAPI up and running. However, clusterctl’s imperative
+design makes it difficult for cluster admins to stand up and manage CAPI
+management clusters in their own preferred way.
+
+This proposal provides a solution that leverages a declarative API and an
+operator to empower admins to handle the lifecycle of providers within the
+management cluster.
+
+## Motivation
+
+In its current form clusterctl is designed to provide a simple user experience
+for day 1 operations of a Cluster API management cluster.
+
+However such design is not optimized for supporting declarative approaches
+when operating Cluster API management clusters.
+
+These declarative approaches are important to enable GitOps workflows in case
+users don't want to rely solely on the `clusterctl` CLI.
+
+Providing a declarative API also enables us to leverage controller-runtime's
+new component config and allow us to configure the controller manager and even
+the resource limits of the provider's deployment.
+
+Another example is improving cluster upgrades. In order to upgrade a cluster
+we now need to supply all the information that was provided initially during a
+`clusterctl init` which is inconvenient in many cases such as distributed
+teams and CI pipelines where the configuration needs to be stored and synced
+externally.
+
+With the management cluster operator, we aim to address these use cases by
+introducing an operator that handles the lifecycle of providers within the
+management cluster based on a declarative API.
+
+### Goals
+
+- Define an API that enables declarative management of the lifecycle of
+  Cluster API and all of its providers.
+- Support air-gapped environments through sufficient documentation initially.
+- Identify and document differences between clusterctl CLI and the operator in
+  managing the lifecycle of providers, if any.
+- Define how the clusterctl CLI should be changed in order to interact with
+  the management cluster operator in a transparent and effective way.
+- To support the ability to upgrade from a v1alpha3 based version (v0.3.[TBD])
+  of Cluster API to one managed by the operator.
+
+### Non-Goals/Future Work
+
+- `clusterctl` will not be deprecated or replaced with another CLI.
+- Implement an operator driven version of `clusterctl move`.
+- Manage cert-manager using the operator.
+- Support multiple installations of the same provider within a management
+  cluster in light of [issue 3042] and [issue 3354].
+- Support any template processing engines.
+- Support the installation of v1alpha3 providers using the operator.
+
+## Proposal
+
+### User Stories
+
+1. As an admin, I want to use a declarative style API to operate the Cluster
+   API providers in a management cluster.
+1. As an admin, I would like to have an easy and declarative way to change
+   controller settings (e.g. enabling pprof for debugging).
+1. As an admin, I would like to have an easy and declarative way to change the
+   resource requirements (e.g. such as limits and requests for a provider
+   deployment).
+1. As an admin, I would like to have the option to use clusterctl CLI as of
+   today, without being concerned about the operator.
+1. As an admin, I would like to be able to install the operator using kubectl
+   apply, without being forced to use clusterctl.
+
+### Implementation Details/Notes/Constraints
+
+### Clusterctl
+
+The `clusterctl` CLI will provide a similar UX to the users whilst leveraging
+the operator for the functions it can. As stated in the Goals/Non-Goals, the
+move operation will not be driven by the operator but rather remain within the
+CLI for now. However, this is an implementation detail and will not affect the
+users.
+
+#### Existing API Types Changes
+
+The existing `Provider` type used by the clusterctl CLI will be deprecated and
+its instances will be migrated to instances of the new API types as defined in
+the next section.
+
+The management cluster operator will be responsible for migrating the existing
+provider types to support GitOps workflows excluding `clusterctl`.
+
+#### New API Types
+
+These are the new API types being defined.
+
+There are separate types for each provider type - Core, Bootstrap,
+ControlPlane, and Infrastructure. However, since each type is similar, their
+Spec and Status uses the shared types - `ProviderSpec`,  `ProviderStatus`
+respectively.
+
+We will scope the CRDs to be namespaced. This will allow us to enforce
+RBAC restrictions if needed. This also allows us to install multiple
+versions of the controllers (grouped within namespaces) in the same
+management cluster although this scenario will not be supported natively in
+the v1alpha4 iteration.
+
+If you prefer to see how the API can be used instead of reading the type
+definition feel free to jump to the [Example API Usage
+section](#example-api-usage)
+

+
+**Validation and defaulting rules for Provider and ProviderSpec**
+- The `Name` field within `metav1.ObjectMeta` could be any valid Kubernetes
+  name; however, it is recommended to use Cluster API provider names. For
+  example, aws, vsphere, kubeadm. These names will be used to fetch the
+  default configurations in case there is no specific FetchConfiguration
+  defined.
+- `ProviderSpec.Version` should be a valid default version with the "v" prefix
+  as commonly used in the Kubernetes ecosystem; if this value is nil when a
+  new provider is created, the operator will determine the version to use
+  applying the same rules implemented in clusterctl (latest).
+  Once the latest version is calculated it will be set in
+  `ProviderSpec.Version`.
+- Note: As per discussion in the CAEP PR, we will keep the `SecretName` field
+  to allow the provider authors ample time to implement their own credential
+  management to support multiple workload clusters. [See this thread for more
+  info][secret-name-discussion].
+
+**Validation rules for ProviderSpec.FetchConfiguration**
+- If the FetchConfiguration is empty and not defined, then the operator will
+  apply the embedded fetch configuration for the given kind and
+  `ObjectMeta.Name`. For example, the infrastructure name `aws` will fetch
+  artifacts from
+  https://github.com/kubernetes-sigs/cluster-api-provider-aws/releases.
+- If FetchConfiguration is not nil, exactly one of `URL` or `Selector` must be
+  specified.
+- `FetchConfiguration.Selector` is used to fetch provider’s components and
+  metadata from ConfigMaps stored inside the cluster. Each ConfigMap is
+  expected to contain components and metadata for a specific version only. So
+  if multiple versions of the providers need to be specified, they can be
+  added as separate ConfigMaps and labeled with the same selector. This
+  provides the same behavior as the “local” provider repositories but now from
+  within the management cluster.
+- `FetchConfiguration` is used only during init and upgrade operations.
+  Changes made to the contents of `FetchConfiguration` will not trigger a
+  reconciliation. This is similar behavior to `ProviderSpec.SecretName`.
+
+**Validation Rules for ProviderSpec.ManagerSpec**
+- The ControllerManagerConfigurationSpec is a type from
+  `controller-runtime/pkg/config` and is an embedded into the `ManagerSpec`.
+  This type will expose LeaderElection, SyncPeriod, Webhook, Health and
+  Metrics configurations.
+- If `ManagerSpec.Debug` is set to true, the operator will not allow changes
+  to other properties since it is in Debug mode.
+- If you need to set specific concurrency values for each reconcile loop (e.g.
+  `awscluster-concurrency`), you can leave
+  `ManagerSpec.MaxConcurrentReconciles` nil and use `Container.Args`.
+- If `ManagerSpec.MaxConcurrentReconciles` is set and a specific concurrency
+  flag such as `awscluster-concurrency` is set on the `Container.Args`, then
+  the more specific concurrency flag will have higher precedence.
+
+
+**Validation Rules for ContainerSpec**
+- The `ContainerSpec.Args` will ignore the key `namespace` since the operator
+  enforces a deployment model where all the providers should be configured to
+  watch all the namespaces.
+- Explicit controller manager properties defined in the `Provider.ManagerSpec`
+  will have higher precedence than those defined in `ContainerSpec.Args`. That
+  is, if `ManagerSpec.SyncPeriod` is defined it will be used instead of the
+  container arg `sync-period`. This is true also for
+  `ManagerSpec.FeatureGates`, that is, it will have higher precedence to the
+  container arg `feature-gates`.
+- If no `ContainerSpec.Resources` are defined, the defaults on the Deployment
+  object within the provider’s components yaml will be used.
+
+
+#### Example API Usage
+
+1. As an admin, I want to install the aws infrastructure provider with
+   specific controller flags.

+apiVersion: management.cluster.x-k8s.io/v1alpha1
+kind: InfrastructureProvider
+metadata:
+ name: aws
+ namespace: capa-system
+spec:
+ version: v0.6.0
+ secretName: aws-variables
+ manager:
+   # These top level controller manager flags, supported by all the providers.
+   # These flags come with sensible defaults, thus requiring no or minimal

+   - name: manager
+     args:
+         # These are controller flags that are specific to a provider; usage
+         # is reserved for advanced scenarios only.
+         awscluster-concurrency: 12
+         awsmachine-concurrency: 11
+```
+
+2. As an admin, I want to install aws infrastructure provider but override
+   the container image of the CAPA deployment.
+
+```yaml
+---
+apiVersion: management.cluster.x-k8s.io/v1alpha1
+kind: InfrastructureProvider
+metadata:
+ name: aws
+ namespace: capa-system
+spec:
+ version: v0.6.0
+ secretName: aws-variables
+ deployment:
+   containers:
+   - name: manager
+     image: gcr.io/myregistry/capa-controller:v0.6.0-foo
+```
+
+3. As an admin, I want to change the resource limits for the manager pod in
+   my control plane provider deployment.
+
+```yaml
+---
+apiVersion: management.cluster.x-k8s.io/v1alpha1
+kind: ControlPlaneProvider
+metadata:
+ name: kubeadm
+ namespace: capi-kubeadm-control-plane-system
+spec:
+ version: v0.3.10
+ secretName: capi-variables
+ deployment:
+   containers:
+   - name: manager
+     resources:
+       limits:
+         cpu: 100m
+         memory: 30Mi
+       requests:
+         cpu: 100m
+         memory: 20Mi
+```
+
+4. As an admin, I would like to fetch my azure provider components from a
+   specific repository which is not the default.
+
+```yaml
+---
+apiVersion: management.cluster.x-k8s.io/v1alpha1
+kind: InfrastructureProvider
+metadata:
+ name: myazure
+ namespace: capz-system
+spec:
+ version: v0.4.9
+ secretName: azure-variables
+ fetchConfig:
+   url: https://github.com/myorg/awesome-azure-provider/releases
+
+```
+
+5. As an admin, I would like to use the default fetch configurations by
+   simply specifying the expected Cluster API provider names such as 'aws',
+   'vsphere', 'azure', 'kubeadm', 'talos', or 'cluster-api' instead of having
+   to explicitly specify the fetch configuration.
+   In the example below, since we are using 'vsphere' as the name of the
+   InfrastructureProvider the operator will fetch it's configuration from
+   `url: https://github.com/kubernetes-sigs/cluster-api-provider-vsphere/releases`
+   by default.
+
+See more examples in the [air-gapped environment section](#air-gapped-environment)
+
+```yaml
+---
+apiVersion: management.cluster.x-k8s.io/v1alpha1
+kind: InfrastructureProvider
+metadata:
+ name: vsphere
+ namespace: capv-system
+spec:
+ version: v0.4.9
+ secretName: vsphere-variables
+
+```
+
+#### Operator Behaviors
+
+##### Installing a provider
+
+In order to install a new Cluster API provider with the management cluster
+operator you have to create a provider as shown above. See the first example
+API usage to create the secret with variables and the provider itself.
+
+When processing a Provider object the operator will apply the following rules.
+
+- Providers with  `spec.Type == CoreProvider` will be installed first; the
+  other providers will be requeued until the core provider exists.
+- Before installing any provider following preflight checks will be executed :
+    - There should not be another instance of the same provider (same Kind, same
+      name) in any namespace.
+    - The Cluster API contract the provider is abiding by, e.g. v1alpha4, must
+      match the contract of the core provider.
+- The operator will set conditions on the Provider object to surface any
+  installation issues such as pre-flight checks and/or order of installation
+  to accurately inform the user.
+- Since the FetchConfiguration is empty and not defined, the operator will
+  apply the embedded fetch configuration for the given kind and
+  `ObjectMeta.Name`. In this case, the operator will fetch artifacts from
+  https://github.com/kubernetes-sigs/cluster-api-provider-aws/releases.
+
+The installation process managed by the operator is consistent with the
+implementation underlying the `clusterctl init` command and includes the
+following steps:
+- Fetching the provider artifacts (the components yaml and the metadata.yaml
+  file).
+- Applying image overrides, if any.
+- Replacing variables in the infrastructure-components from EnvVar and
+  Secret.
+- Applying the resulting yaml to the cluster.
+
+As a final consideration, please note that
+- The operator executes installation for 1 provider at time, while `clusterctl
+  init` manages installation of a group of providers with a single operation.
+- `clusterctl init` uses environment variables and a local configuration file,
+  while the operator uses a Secret; given that we want the users to preserve
+  current behaviour in clusterctl, the init operation should be modified to
+  transfer local configuration to the cluster.
+  As part of `clusterctl init`, it will obtain the list of variables required
+  by the provider components and read the corresponding values from the config
+  or environment variables and build the secret.
+  Any image overrides defined in the clusterctl config will also be applied to
+  the provider's components.
+
+In the following figure, the controllers for the providers are installed in
+the namespaces that are defined by default.
+
+![Figure 1](./images/capi-provider-operator/fig3.png "Figure for
+installing providers in defined namespaces")
+<div align="center">Installing providers in defined namespaces</div>
+<br/>
+
+In the following figure, the controllers for the providers are all installed in
+the same namespace as configured by the user.
+
+![Figure 2](./images/capi-provider-operator/fig4.png "Figure for
+installing all providers in the same namespace")
+<div align="center">Installing all providers in the same namespace</div>
+<br/>
+
+##### Upgrading a provider
+
+In order to trigger an upgrade of a new Cluster API provider you have to
+change the `spec.Version` field.
+
+Upgrading a provider in the management cluster must abide by the golden rule
+that all the providers should respect the same Cluster API contract supported
+by the core provider.
+
+##### Upgrades providers without changing contract
+
+If the new version of the provider does abide by the same version of the
+Cluster API contract, the operator will execute the upgrade by performing:
+- Delete of the current instance of the provider components, while preserving
+  CRDs, namespace and user objects.
+- Install the new version of the provider components
+
+Please note that:
+- The operator executes upgrades 1 provider at time, while `clusterctl upgrade
+  apply` manages upgrading a group of providers with a single operation.
+- `clusterctl upgrade apply --contract` automatically determines the latest
+  versions available for each provider, while with the Declarative approach
+  the user is responsible for manually editing Provider objects yaml.
+- `clusterctl upgrade apply` currently uses environment variables and a local
+  configuration file; this should be changed in order to use in cluster
+  provider configurations.
+
+![Figure 3](./images/capi-provider-operator/fig1.png "Figure for
+upgrading provider without changing contract")
+<div align="center">Upgrading providers without changing contract</div>
+<br/>
+
+##### Upgrades providers and changing contract
+
+If the new version of the provider does abide by a new version of the Cluster
+API contract, it is required to ensure all the other providers in the
+management cluster should get the new version too.
+
+![Figure 4](./images/capi-provider-operator/fig2.png "Figure for
+upgrading provider and changing contract")
+<div align="center">Upgrading providers and changing contract</div>
+<br/>
+
+As a first step, it is required to pause all the providers by setting the
+`spec.Paused` field to true for each provider; the operator will block any
+contract upgrade until all the providers are paused.
+
+After all the providers are in paused state, you can proceed with the upgrade
+as described in the previous paragraph (change the `spec.Version` field).
+
+When a provider is paused the number of replicas will be scaled to 0; the
+operator will add a new
+`management.cluster.x-k8s.io/original-controller-replicas` annotation to store
+the original replica count.
+
+Once all the providers are upgraded to a version that abides to the new
+contract, it is possible for the operator to unpause providers; the operator
+does not allow to unpause providers if there are still providers abiding to
+the old contract.
+
+Please note that we are planning to embed this sequence (pause - upgrade -
+unpause) as a part of `clusterctl upgrade apply` command when there is a
+contract change.
+
+##### Changing a provider
+
+On top of changing a provider version (upgrades), the operator supports also
+changing other provider fields, most notably controller flags and variables.
+This can be achieved by either `kubectl edit` or `kubectl apply` to the
+provider object.
+
+The operation internally works like upgrades: The current instance of the
+provider is deleted, while preserving CRDs, namespaced and user objects A new
+instance of the provider is installed with the new set of flags/variables.
+
+Please note that clusterctl currently does not support this operation.
+
+See Example 1 in [Example API Usage](#example-api-usage)
+
+##### Deleting a provider
+
+In order to delete a provider you have to delete the corresponding provider
+object.
+
+Deletion of the provider will be blocked if any workload cluster using the
+provider still exists.
+
+Additionally, deletion of a core provider should be blocked if there are still
+other providers in the management cluster.
+
+#### Upgrade from v1alpha3 management cluster to v1alpha4 cluster
+
+Cluster API will provide instructions on how to upgrade from a v1alpha3
+management cluster, created by clusterctl to the new v1alpha4 management
+cluster. These operations could require manual actions.
+
+Some of the actions are described below:
+- Run webhooks as part of the main manager. See [issue 3822].
+
+More details will be added as we better understand what a v1alpha4 cluster
+will look like.
+
+#### Operator Lifecycle Management
+
+##### Operator Installation
+
+- `clusterctl init` will install the operator and its corresponding CRDs as a
+  pre-requisite if the operator doesn’t already exist. Please note that this
+  command will consider image overrides defined in the local clusterctl config
+  file.
+- If the admin does not want to use clusterctl to install the operator, it is
+  possible to `kubectl apply` the operator yaml that will be published in the
+  cluster-api release artifacts.
+
+##### Operator Upgrade
+
+- The admin can use `clusterctl upgrade operator` to upgrade the operator
+  components. Please note that this command will consider image overrides
+  defined in the local clusterctl config file. Other commands such as
+  `clusterctl upgrade apply` will also allow to upgrade the operator.
+- `clusterctl upgrade plan` will identify when the operator can be upgraded by
+  checking the cluster-api release artifacts.
+- If the admin doesn’t want to use clusterctl, they can use kubectl apply with
+  the latest version of the operator yaml that will be published in the
+  cluster-api release artifacts.
+- clusterctl will require a matching operator version. In the future, when
+  clusterctl move to beta/GA, we will reconsider supporting version skew
+  between clusterctl and the operator.
+
+##### Operator Delete
+
+- clusterctl will delete the operator as part of the `clusterctl delete --all`
+  command.
+- If the admin doesn’t want to use clusterctl, they can use kubectl delete.
+  However, it’s the admin’s responsibility to verify that there are no
+  providers running in the management cluster.
+
+#### Air gapped environment
+
+In order to install Cluster API providers in an air-gapped environment using
+the operator, it is required to address the following issues.
+
+1. Make the operator work in air-gapped environment
+   - To provide image overrides for the operator itself in order to pull the
+     images from an accessible image repository. Please note that the
+     overrides will be considered from the image overrides defined in the
+     local clusterctl config file.
+   - TBD if operator yaml will be embedded in clusterctl or if it should be a
+     special artifact within the core provider repository.
+1. Make the providers work in air-gapped environment
+   - To provide fetch configuration for each provider reading from an
+     accessible location (e.g. an internal github repository) or from
+     ConfigMaps pre-created inside the cluster.
+   - To provide image overrides for each provider in order to pull the images
+     from an accessible image repository.
+
+**Example Usage**
+
+As an admin, I would like to fetch my azure provider components from within
+the cluster because I’m working within an air-gapped environment.
+
+In this example, we have two config maps that define the components and
+metadata of the provider. They each share the label `provider-components:
+azure` and are within the `capz-system` namespace.
+
+The azure InfrastructureProvider has a `fetchConfig` which specifies the label
+selector. This way the operator knows which versions of the azure provider are
+available. Since the provider’s version is marked as `v0.4.9`, it uses the
+components information from the config map to install the azure provider.
+
+```yaml
+---
+apiVersion: v1
+kind: ConfigMap
+metadata:
+ labels:
+   provider-components: azure
+ name: v0.4.9
+ namespace: capz-system
+data:
+ components: |
+ # components for v0.4.9 yaml goes here
+ metadata: |
+ # metadata information goes here
+---
+apiVersion: v1
+kind: ConfigMap
+metadata:
+ labels:
+   provider-components: azure
+ name: v0.4.8
+ namespace: capz-system
+data:
+ components: |
+ # components for v0.4.8 yaml goes here
+ metadata: |
+ # metadata information goes here
+---
+apiVersion: management.cluster.x-k8s.io/v1alpha1
+kind: InfrastructureProvider
+metadata:
+ name: azure
+ namespace: capz-system
+spec:
+ version: v0.4.9
+ secretName: azure-variables
+ fetchConfig:
+   selector:
+     matchLabels:
+       provider-components: azure
+```
+
+### Risks and Mitigation
+
+#### Error Handling & Logging
+
+Currently, clusterctl provides quick feedback regarding required variables
+etc. With the operator in place we’ll need to ensure that the error messages
+and logs are easily available to the user to verify progress.
+
+#### Extensibility Options
+
+Currently, clusterctl has a few extensibility options.  For example,
+clusterctl is built on-top of a library that can be leveraged to build other
+tools.
+
+It also exposes an interface for template processing if we choose to go a
+different route from `envsubst`. This may prove to be challenging in the
+context of the operator as this would mean a change to the operator
+binary/image. We could introduce a new behavior or communication protocol or
+hooks for the operator to interact with the custom template processor. This
+could be configured similarly to the fetch config, with multiple options built
+in.
+
+We have decided that supporting multiple template processors is a non-goal for
+this implementation of the proposal and we will rely on using the default
+`envsubst` template processor.
+
+#### Upgrade from v1alpha3 management cluster to v1alpha4/operator cluster
+
+As of today, this is hard to define as have yet to understand the definition
+of what a v1alpha4 cluster will be. Once we better understand what a v1alpha4
+cluster will look like, we will then be able to determine the upgrade sequence
+from v1alpha3.
+
+Cluster API will provide instructions on how to upgrade from a v1alpha3
+management cluster, created by clusterctl to the new v1alpha4 management
+cluster. These operations could require manual actions.
+
+Some of the actions are described below:
+- Run webhooks as part of the main manager. See [issue
+  3822](https://github.com/kubernetes-sigs/cluster-api/issues/3822)
+
+## Additional Details
+
+### Test Plan
+
+The operator will be written with unit and integration tests using envtest and
+existing patterns as defined under the [Developer
+Guide/Testing](https://cluster-api.sigs.k8s.io/developer/testing.html) section
+in the Cluster API book.
+
+Existing E2E tests will verify that existing clusterctl commands such as `init`
+and `upgrade` will work as expected. Any necessary changes will be made in
+order to make it configurable.
+
+New E2E tests verifying the operator lifecycle itself will be added.
+
+New E2E tests verifying the upgrade from a v1alpha3 to v1alpha4 cluster will
+be added.
+
+### Version Skew Strategy
+
+- clusterctl will require a matching operator version. In the future, when
+  clusterctl move to beta/GA, we will reconsider supporting version skew
+  between clusterctl and the operator.

+
+### Managed cluster infrastructure
+
+Cluster infrastructure whose lifecycle is managed by a provider InfraCluster controller.
+E.g. in AWS:
+- Network
+    - VPC
+    - Subnets
+    - Internet gateways
+    - Nat gateways
+    - Route tables
+- Security groups
+- Load balancers
+
+### Externally managed cluster infrastructure
+
+An InfraCluster resource (usually part of an infrastructure provider) whose lifecycle is managed by an external controller.
+
+## Summary
+
+This proposal introduces support to allow infrastructure cluster resources (e.g. AzureCluster, AWSCluster, vSphereCluster, etc.) to be managed by an external controller or tool.
+
+## Motivation
+
+Currently, Cluster API infrastructure providers support an opinionated happy path to create and manage cluster infrastructure lifecycle.
+The fundamental use case we want to support is out of tree controllers or tools that can manage these resources.
+
+For example, users could create clusters using tools such as Terraform, Crossplane, or Kops and run CAPI on top of installed infrastructure.
+
+The proposal might also ease adoption of Cluster API in heavily restricted environments where the provider infrastructure for the cluster needs to be managed out of band.
+
+### Goals
+
+- Introduce support for "externally managed" cluster infrastructure consistently across Cluster API providers.
+- Any machine controller or machine infrastructure controllers must be able to keep operating like they do today.
+- Reuse existing InfraCluster CRDs in "externally managed" clusters to minimise differences between the two topologies.
+
+### Non-Goals/Future Work
+
+- Modify existing managed behaviour.
+- Automatically mark InfraCluster resources as ready (this will be up to the external management component initially).
+- Support anything other than cluster infrastructure (e.g. machines).
+
+## Proposal
+
+A new annotation `cluster.x-k8s.io/managed-by: "<name-of-system>"` is going to be defined in Cluster API core repository, which helps define and identify resources managed by external controllers. The value of the annotation will not be checked by Cluster API and is considered free form text.
+
+Infrastructure providers SHOULD respect the annotation and its contract.
+
+When this annotation is present on an InfraCluster resource, the InfraCluster controller is expected to ignore the resource and not perform any reconciliation.
+Importantly, it will not modify the resource or its status in any way.
+A predicate will be provided in the Cluster API repository to aid provider implementations in filtering resources that are externally managed.
+
+Additionally, the external management system must provide all required fields within the spec of the InfraCluster and must adhere to the CAPI provider contract and set the InfraCluster status to be ready when it is appropriate to do so.
+
+While an "externally managed" InfraCluster won't reconcile or manage the lifecycle of the cluster infrastructure, CAPI will still be able to create compute nodes within it.
+
+The machine controller must be able to operate without hard dependencies regardless of the cluster infrastructure being managed or externally managed.
+![](https://i.imgur.com/nA61XJt.png)
+
+### User Stories
+
+#### Story 1 - Alternate control plane provisioning with user managed infrastructure
+As a cluster provider I want to use CAPI in my service offering to orchestrate Kubernetes bootstrapping while letting workload cluster operators own their infrastructure lifecycle.
+
+For example, Cluster API Provider AWS only supports a single architecture for delivery of network resources for cluster infrastructure, but given the possible variations in network architecture in AWS, the majority of organisations are going to want to provision VPCs, security groups and load balancers themselves, and then have Cluster API Provider AWS provision machines as normal. Currently CAPA supports "bring your own infrastructure" when users fill in the `AWSCluster` spec, and then CAPA reconciles any missing resources. This has been done in an ad hoc fashion, and has proven to be a frequently brittle mechanism with many bugs. The AWSMachine controller only requires a subset of the AWSCluster resource in order to reconcile machines, in particular - subnet, load balancer (for control plane instances) and security groups. Having a formal contract for externally managed infrastructure would improve the user experience for those getting started with Cluster API and have non-trivial networking requirements.
+
+#### Story 2 - Restricted access to cloud provider APIs
+As a cluster operator I want to use CAPI to orchestrate kubernetes bootstrapping while restricting the privileges I need to grant for my cloud provider because of organisational cloud security constraints.
+
+#### Story 3 - Consuming existing cloud infrastructure
+As a cluster operator I want to use CAPI to orchestrate Kubernetes bootstrapping while reusing infrastructure that has already been created in the organisation either by me or another team.
+
+Following from the example in Story 1, many AWS environments are tightly governed by an organisation's cloud security operations unit, and provisioning of security groups in particular is often prohibited.
+
+### Implementation Details/Notes/Constraints
+
+**Managed**
+
+- It will be default and will preserve existing behaviour. An InfraCluster CR without the `cluster.x-k8s.io/managed-by: "<name-of-system>"` annotation.
+
+
+**Externally Managed**
+
+An InfraCluster CR with the `cluster.x-k8s.io/managed-by: "<name-of-system>"` annotation.
+
+The provider InfraCluster controller must:
+- Skip any reconciliation of the resource.
+
+- Not update the resource or its status in any way
+
+The external management system must:
+
+- Populate all required fields within the InfraCluster spec to allow other CAPI components to continue as normal.
+
+- Adhere to all Cluster API contracts for infrastructure providers.
+
+- When the infrastructure is ready, set the appropriate status as is done by the provider controller today.
+
+#### Provider implementation changes
+
+To enable providers to implement the changes required by this contract, Cluster API is going to provide a new `predicates.ResourceExternallyManaged` predicate as part of its utils.
+
+This predicate filters out any resource that has been marked as "externally managed" and prevents the controller from reconciling the resource.
+
+### Security Model
+
+When externally managed, the required cloud provider privileges required by CAPI might be significantly reduced when compared with a traditionally managed cluster.
+The only privileges required by CAPI are those that are required to manage machines.
+
+For example, when an AWS cluster is managed by CAPI, permissions are required to be able to create VPCs and other networking components that are managed by the AWSCluster controller. When externally managed, these permissions are not required as the external entity is responsible for creating such components.
+
+Support for minimising permissions in Cluster API Provider AWS will be added to its IAM provisioning tool, `clusterawsadm`.
+
+### Risks and Mitigations
+
+#### What happens when a user converts an externally managed InfraCluster to a managed InfraCluster?
+
+There currently is no immutability support for CRD annotations within the Kubernetes API.
+
+This means that, once a user has created their externally managed InfraCluster, they could at some point, update the annotation to make the InfraCluster appear to be managed.
+
+There is no way to predict what would happen in this scenario.
+The InfraCluster controller would start attempting to reconcile infrastructure that it did not create, and therefore, there may be assumptions it makes that mean it cannot manage this infrastructure.
+
+To prevent this, we will have to implement (in the InfraCluster webhook) a means to prevent users converting externally managed InfraClusters into managed InfraClusters.
+
+Note however, converting from managed to externally managed should cause no issues and should be allowed.
+It will be documented as part of the externally managed contract that this is a one way operation.
+
+### Future Work
+
+#### Marking InfraCluster ready manually
+
+The content of this proposal assumes that the management of the external infrastructure is done by some controller which has the ability to set the spec and status of the InfraCluster resource.
+
+In reality, this may not be the case. For example, if the infrastructure was created by an admin using Terraform.
+
+When using a system such as this, a user can copy the details from the infrastructure into an InfraCluster resource and create this manually.
+However, they will not be able to set the InfraCluster to ready as this requires updating the resource status which is difficult when not using a controller.
+
+To allow users to adopt this external management pattern without the need for writing their own controllers or tooling, we will provide a longer term solution that allows a user to indicate that the infrastructure is ready and have the status set appropriately.
+
+The exact mechanism for how this will work is undecided, though the following ideas have been suggested:
+
+- Reuse of future kubectl subresource flag capabilities https://github.com/kubernetes/kubernetes/pull/99556.
+
+- Add a secondary annotation to this contract that causes the provider InfraCluster controller to mark resources as ready
+
+## Alternatives
+
+### ExternalInfra CRD
+
+We could have an adhoc CRD https://github.com/kubernetes-sigs/cluster-api/issues/4095
+
+This would introduce complexity for the CAPI ecosystem with yet an additional CRD and it wouldn't scale well across providers as it would need to contain provider specific information.
+
+### ManagementPolicy field
+
+As an alternative to the proposed annotation, a `ManagementPolicy` field on Infrastructure Cluster spec could be required as part of this contract.
+The field would be an enum that initially has 2 possible values: managed and unmanaged.
+That would require a new provider contract and modification of existing infrastructure CRDs, so this option is not preferred.
+
+## Upgrade Strategy
+
+Support is introduced by adding a new annotation for the provider infraCluster.
+
+This makes any transition towards an externally managed cluster backward compatible and leave the current managed behaviour untouched.

+
+## Summary
+
+Make CABPK and KCP to use more recent versions of the kubeadm API and insulate users from
+kubeadm API version changes.
+
+## Motivation
+
+Cluster bootstrap provider for kubeadm (CABPK) and the control plane provider for kubeadm
+(KCP) API still relying on kubeadm v1beta1 API, which has been deprecated, and it is going
+to be removed ASAP.
+
+While moving to a more recent version of the kubeadm API is a required move, Cluster API
+should take this opportunity to stop relying on the assumption that the kubeadm API types in the
+KubeadmConfig/KubeadmControlPlane specs are supported(1) by all the Kubernetes/kubeadm version
+in the support range.
+
+This would allow to separate what users fill in the KubeadmConfig/KubeadmControlPlane
+from which kubeadm API version Cluster API end up using in the bootstrap data.
+
+(1) Supported in this context means that the serialization format of the types is the same,
+because types are already different (see background info in the implementation details paragraph).
+
+### Goals
+
+- Define a stop-gap for using the most recent version of the kubeadm API in Cluster API
+  v1alpha3 - introducing any breaking changes.
+- Define how to stop to exposing the kubeadm v1betax types in the KubeadmConfig/KubeadmControlPlane
+  specs for v1alpha4.
+- Define how to use the right version of the kubeadm types generating our kubeadm yaml
+  file and when interacting with the kubeadm-config ConfigMap.
+- Ensure a clean and smooth v1alpha3 to v1aplha4 upgrade experience.
+
+### Non-Goals
+
+- Adding or removing fields in KubeadmConfig/KubeadmControlPlane spec.
+- Introduce behavioral changes in CABPK or KCP.
+
+### Future work
+
+- Evaluate improvements for the Cluster API owned version of KubeadmConfig/KubeadmControlPlane
+  specs types.
+- Make it possible for the Cluster API users to take benefit of changes introduced
+  in recent versions of the Kubeadm API.
+
+## Proposal
+
+### User Stories
+
+#### Story 1
+
+As a user, I want to user kubeadm providers for Cluster API (CABPK & KPC) in the same
+way across the entire spectrum of supported kubernetes versions.
+
+#### Story 2
+
+As the kubeadm tool, I want the kubeadm providers for Cluster API (CABPK & KPC) to
+use the latest kubeadm API supported by the target kubeadm/kubernetes version.
+
+### Requirements
+
+R1 - avoid breaking changes in v1alpha3
+R2 - ensure a clean v1alpha3 to v1alpha4 upgrade
+
+### Implementation Details/Notes/Constraints
+
+#### Background info about kubeadm API version
+
+kubeadm v1beta1 types:
+
+- Introduced in v1.13.
+- Deprecation cycle started with v1.17.
+- Removal scheduled for v1.20 but then postponed to v1.21.
+
+kubeadm v1beta2 types:
+
+- Introduced in v1.15.
+- Changes from the previous version are minimal:
+  - Support for IgnorePreflightErrors into the NodeRegistrationOptions.
+  - Support for CertificateKey into InitConfiguration and JoinConfiguration
+    configuration (not relevant for Cluster API because it is not using the
+    automatic certificate copy feature).
+  - improved serialization support (in practice a set of `omitempty` fixes).
+
+#### Background info about kubeadm types into the KubeadmConfig/KubeadmControlPlane specs
+
+Given the fact that importing kubeadm (which is part of the Kubernetes codebase)
+in Cluster API is impractical, Cluster API hosts a mirror of kubeadm API types.
+
+kubeadm v1beta1 mirror-types:
+
+- Hosted in `bootstrap/kubeadm/types/v1beta1`.
+- Diverged from the original v1beta1 types for better CRD support (in practice
+  a set of `+optional` fixes, few `omitempty` differences).
+
+kubeadm v1beta2 mirror-types:
+
+- Hosted in `bootstrap/kubeadm/types/v1beta2`.
+- Currently, not used in the Cluster API codebase.
+- Does not include changes for better CRD support introduced in kubeadm v1beta1
+  mirror-types.
+
+#### Cluster API v1alpha3 changes
+
+Changes to cluster API v1alpha3 release should be minimal and no breaking change
+should be introduced while implementing this proposal.
+
+According to this principle and to the feedback to this proposal,
+we are going to implement alternative 2 described below.
+
+__Alternative 1:__
+
+Keep kubeadm v1beta1 types as a Hub type (1); implement conversion to kubeadm API
+version f(Kubernetes Version) when generating the kubeadm config for init/join (
+e.g convert to kubeadm API v1beta2 for Kubernetes version >= v1.15, convert to 
+kubeadm API v1beta1 for Kubernetes version < v1.15).
+
+This alternative is the more clean, robust and forward looking, but it requires
+much more work than alternative 2.
+
+__Alternative 2:__
+
+Keep kubeadm v1beta1 types as a Hub type (1); only change the apiVersion to
+`kubeadm.k8s.io/v1beta2` in the generated kubeadm config for init/join.
+
+This alternative is based on following considerations:
+
+- kubeadm v1beta1 mirror types are "compatible" with kubeadm v1beta2 types
+  - Having support for IgnorePreflightErrors into the NodeRegistrationOptions
+    is not required for Cluster API v1alpha3
+  - The automatic certificate copy feature is not used by Cluster API
+  - Improved serialization support has been already applied to the kubeadm
+    v1beta1 mirror-types (and further extended).
+- the minimal Kubernetes version supported by Cluster API is v1.16, and kubeadm
+  v1.16 could work with v1beta2 types. Same for all the other versions up to latest(1.20)
+  and next (1.21).
+- limitations: this approach is not future proof, and it should be reconsidered
+  whenever a new version of kubeadm types is created while v1alpha3 is still supported.
+
+__Common considerations for both alternatives__
+
+KCP is modifying the kubeadm-config Config Map generated by kubeadm, and ideally also
+this bit of code should be made kubeadm version aware.
+
+However, given that the current implementation currently uses unstructured, and
+a change for using the kubeadm types, requires a big refactor, the proposed approach
+for v1alpha3 is to limit the changes to only upgrade the apiVersion when required.
+
+- limitations: this approach is not future proof, and it should be reconsidered
+  whenever a new version of kubeadm types is changing one of the fields
+  edited during upgrades.
+
+(1) See https://book.kubebuilder.io/multiversion-tutorial/conversion-concepts.html
+for a definition of Hub or spoke types/version.
+
+#### Cluster API v1alpha4 changes
+
+Changes to cluster API v1alpha4 could be more invasive and seek for a
+forward-looking solution.
+
+Planned actions are:
+
+- introduce a Cluster API owned version of the kubeadm config types
+  (starting from kubeadm v1beta1) to be used by KubeadmConfig/KubeadmControlPlane
+  specs; this should also act as a serialization/deserialization hub (1).
+  Please note that those types will be part of Cluster API types, and thus initially 
+  versioned as v1alpha4; once conversion will be in place, those types are not required
+  anymore to have the same serialization format of the real kubeadm types.
+- preserve `bootstrap/kubeadm/types/v1beta1` as a serialization/deserialization
+  spoke (1)(2) for v1alpha4 (also, this will be used by v1alpha3 API types until removal)
+- preserve `bootstrap/kubeadm/types/v1beta2` as serialization/deserialization
+  spoke (1)(2) for v1alpha4
+- implement hub/spoke conversions (1)
+- make CABPK to use conversion while generating the kubeadm config file for init/join
+- make KCP to use conversion while serializing/deserializing the kubeadm-config Config Map
+- make KCP to use the Cluster API owned version of the kubeadm config types instead
+  of using `Unstructured` for the kubeadm-config Config Map handling
+- add the `IgnorePreflightError` field to the Cluster API owned types; this field will be silently
+  ignored when converting to v1beta1 (because this version does not support this field).  
+  Note: we are not planning to add `CertificateKey` to the Cluster API owned types because
+  this field is not relevant for Cluster API.
+
+(1) See https://book.kubebuilder.io/multiversion-tutorial/conversion-concepts.html
+for a definition of Hub or spoke types/version.
+(2) As soon as it will be possible to vendor kubeadm types, we should drop this copy 
+and use kubeadm library as a source of truth. Hover there is no concrete plan for this yet.
+
+### Security Model
+
+This proposal does not introduce changes the existing security model.
+
+### Risks and Mitigations
+
+- Time crunch
+
+This change has been postponed several times for different reasons,
+and now it is being worked with a strict deadline before kubeadm type removal.
+Mitigation: Changes to the KubeadmConfig/KubeadmControlPlane specs types considered
+as a future work.
+
+## Alternatives
+
+The `Alternatives` section is used to highlight and record other possible approaches
+to delivering the value proposed by a proposal.
+
+## Upgrade Strategy
+
+Given the requirement to provide a clean upgrade path from v1alpha3 to v1alpha4,
+upgrades should be handles using conversion web-hooks only.
+No external upgrade tool/additional manual steps should be required for upgrade.
+
+## Additional Details
+
+### Test Plan
+
+For v1alpha4 this will be tested by the periodic jobs testing
+creating cluster with different Kubernetes releases, doing upgrades to the next version
+and running Kubernetes conformance.
+
+For v1alpha3 there are no such jobs. We should explore if to backport all the
+required changes to the test framework (complex) or if to create ad-hoc test for this
+using what is supported by the v1alpha3 version of the test framework (possible limitations).

+## Glossary

+- **OID:** Object Identifier defined by the International Telecommunications Union and used in PKI
+  to identify attributes on certificates.
+
+- **PKI:** Public Key Infrastructure
+
+- **TPM:** Trusted Platform Module (TPM) is a specification defined by the Trusted Computing Group
+  (TCG) that allows hosts to attest to their identity via PKI and a secure crypto-processor which
+  may either be a separate chip, built into the CPU or a virtual device provided by the hypervisor.
+
+- **Trust on first use:** Often abbreviated to TOFO is an authentication convention that a provided
+  credential is only trusted from one endpoint which is recorded, and if presented again from a
+  different endpoint it is untrusted. See https://en.wikipedia.org/wiki/Trust_on_first_use for more
+  information.
+
+
+## Summary
+
+This proposal outlines a method to secure node registration within Cluster API, to solve 2 primary
+problems:
+
+- Solve a class of attacks involving node impersonation allowing an attacker to access secrets and
+  volumes they shouldn’t by using hardware attestation of node identity.
+- Reduce kubeadm token reuse in MachinePools where the cloud provider does not support continuous
+  update of the bootstrap userdata without creating new cloud provider specific MachinePool
+  resources (e.g. AWS Launch Configurations).
+
+This node attestation mechanism will be optional in the initial implementation, and can potentially
+be used independently of Cluster API.
+
+## Motivation
+
+Cluster API default core components are largely reliant on kubeadm for cluster bootstrapping and
+node registration. Kubeadm is a platform-agnostic command line tool designed to assist users to
+bootstrap Kubernetes clusters, and is used as a building block in Cluster API. Because kubeadm is
+platform-independent and is intended to provide an “easy path” to cluster bootstrapping,  there are
+a number of inherent design decisions that limit the overall security of the provisioned cluster:
+
+- Kubeadm uses TLS bootstrapping for node registration, however the default workflow used by Cluster
+  API uses bootstrap token which allow registration as arbitrary node names.
+  - When used in this mode, Kubeadm essentially does “client-side validation” to prevent node
+    hijacking, but this does not mean the token cannot be reused by an attacker within the lifetime
+    of the token to perform a hijack. By hijack, the token could be used to auto-approve a CSR
+    for an existing node, and in particular a control plane node such that it then has access to
+    workloads and secrets intended only for control plane instances.
+  - Cluster API cannot scope a token down to a specific node, because neither bootstrap providers,
+    nor most infrastructure providers know the identity of the node ahead of time.
+
+### Goals
+
+- Provide a bootstrap mechanism that assures secure node registration
+- To provide a node registration mechanism that is independent of kubeadm
+- Ensure that this can work with any infrastructure provider
+
+
+### Non-Goals/Future Work
+
+- To change assumptions around management cluster to workload cluster connectivity
+- Solve the protection of initial cluster bootstrap secrets for the control plane nodes
+- To be a mandatory requirement of using Cluster API
+- To implement or enable hardware-backed encryption of traffic between worker nodes and the control
+  plane components.
+
+## Proposal
+
+### User Stories
+
+#### Story 1: Machine Attestation
+
+A cluster operator has been asked to ensure compliance with [NIST SP 800-190 Application Container
+Security][nist-sp-800-190] Guide. Hardware countermeasure 4.6 suggests that container platforms
+should make use of trusted computing. In a Kubernetes context, this would mean providing hardware
+node attestation wherever possible.
+
+#### Story 2: MachinePool race conditions
+
+A cluster operator has set up a MachinePool in either AWS or Azure, and wants the MachinePool to be
+reliable. The current behaviour of Cluster API Bootstrap Provider Kubeadm (CABPK) is such that
+bootstrap tokens are rotated at set intervals, and infrastructure providers must update their
+MachinePool implementations with the new secret data.
+
+This has led to either: implementation specific hacks to ensure the token gets updated, and minor
+race conditions where the infrastructure machine pool implementation does not have the new token
+inserted and attempts to bootstrap the machine with stale bearer tokens.
+
+### Requirements
+
+The node bootstrapper MUST be able to attest the identity of the machine against a chain of trust
+provided by the hardware or cloud provider.
+
+
+### Implementation Details/Notes/Constraints
+
+#### New Components
+
+* **node-attestation-controller**
+  * **Code Location**: Part of Cluster API repository, under bootstrap/node/attestation/controller, and
+    imported by Cluster API infra providers for implementation.
+  * **Release Artifact**: Embedded controller within infrastructure providers.
+  * **Description**: A controller to verify and sign the CSR. This would be typically an importable
+  controller where the infrastructure provider implements the interface with specific code for CSR
+  approval and start the controller as part of its main.go or through an independent binary.
+
+* **kubelet-authenticator**
+  * **Code Location**: Part of Cluster API repository, under bootstrap/node/attestation/authenticator
+    and imported by Cluster API infra providers for implementation.
+generic challenge-response implementation will be included for providers / bare metal without an
+attestation mechanism. This controller runs as part of the Cluster API components in the management
+cluster
+  * **Release Artifact**: Binary for each implementing infrastructure provider called `kubelet-authenticator-<provider>`
+  * **Description**: A controller to verify and sign the CSR. This would be typically an importable
+  controller where the infrastructure provider implements the interface with specific code for CSR
+  approval and start the controller as part of its main.go or through an independent binary.
+
+* **kubelet-authenticator-null**
+  * **Code Location**: Part of CLuster API Provider, under bootstrap/node/attestation/null
+  * **Release Artifact**: None. Used only for testing.
+  * **Description**: A "rubber-stamp" attestor that will validate all CSRs. We will not want to release
+    this as an artifact to prevent it being accidentally used.
+
+#### Kubelet authentication plugin
+
+We propose a kubelet authentication plugin to be present on the instances, (the
+kubelet-authenticator CLI will be baked into the machine images through image-builder), which will
+be responsible for node registration, as well as certificate rotation. The agent will be made up of
+two parts:
+- A common library vendored from Cluster API which includes the following functionality:
+  - Certificate filesystem locking
+  - Checking existing certificate validity
+  - Certificate signing request generation for kubelet client certificates
+  - Submission of CSRs to the API server and waiting for approval
+- A provider specific implementation for node attestation
+  - A provider will need to implement the generation of the attestation to be included in the CSR
+    and the retrieval of the provider ID to be stored in an X.509 extension attribute.
+  - A provider will need to implement checks to verify the SAN attributes of serving certificates.
+
+The behaviour of the authentication plugin will be as follows:
+
+
+#### Node Attestation
+
+As for the node-attestation-controller, the following interface needs to be implemented by the
+infrastructure providers:
+```go
+type ClusterAPISigner interface {
+     VerifyClientAttestationData (csr *certificatesv1beta1.CertificateSigningRequest) err
+     VerifyServingAttestationData (csr *certificatesv1beta1.CertificateSigningRequest) err
+     MachineName (csr *certificatesv1beta1.CertificateSigningRequest) (string, error)
+}
+```
+
+This enables infrastructure providers to perform infrastructure-specific validation of node
+attestations (TPM, appended tags by the provider, etc.)
+
+Cluster API is responsible for partially verifying node identity with the following conditions:
+
+- A corresponding machine object exist for the CSR's `.spec.Username` (`system:nodes:<nodename>`)
+  (providing the value is deferred to infrastructure provider)
+- The Machine must have conditions BootstrapReady.
+- The Kubernetes CSR spec has the needed groups
+- The Kubernetes CSR spec is limited to needed usages (e.g. client auth)
+- The Kubernetes CSR spec is limited to needed extensions (e.g. no CA extension)
+- Parse the CSR and verify that the CN is the same as .spec.username
+- Parse the CSR and verify that the Organization is the same as .spec.Groups
+- Parse the CSR and ensure that no SANs are appended for kubelet client certificates
+
+#### CSR format used by kubelet-authenticator
+We propose the introduction of X.509 extension attributes based
+on those reserved for the Kubernetes GCP cloud provider within Google’s organization ID allocation.
+
+We will request via SIG Architecture or CNCF to apply for an [IANA OID registration
+block][iana-issue] for the Kubernetes project.
+
+##### OIDs
+
+* **OID Suffix**: 2.1.21
+* **Name**: KubernetesNodeProviderIdentifierOID
+* **Description**: An identifier for the machine, should be the same or a derivative of the node
+  provider ID. This is the equivalent of Google’s CloudComputeInstanceIdentifierOID, which we can
+  reuse for a proof of concept (1.3.6.1.4.1.11129.2.1.21).
+
+#### CSR PEM Blocks
+
+The following blocks will be added to CSRs following Section 2 of [RFC7468].
+
+| Block Name                                 | Description                                          |
+| ------------------------------------------ | ---------------------------------------------------- |
+| KUBELET AUTHENTICATOR ATTESTATION PROVIDER | string describing the attestation provider           |
+| KUBELET AUTHENTICATOR ATTESTATION DATA     | the actual attestation data to perform validation on |
+
+#### Attestation data
+
+Attestation data will be appended with the following headers and footers and MUST
+be base64 encoded.
+
+Example CSR:
+```
+-----BEGIN ATTESTATION DATA-----
+S25vd2luZyBtZSBBbGFuIFBhcnRyaWRnZSwga25vd2luZyB5b3UgS3ViZXJuZXRlcyBjbHVzdGVyLCBhaGEh
+-----END ATTESTATION DATA-----
+```
+The format of the attestation block is left to the provider.
+
+#### Core Specification
+- Core Cluster API MUST provide the following implementations of CSRs and signers:
+  - `cluster.x-k8s.io/kube-apiserver-client-kubelet-insecure` which implement an “Always Allow” type
+    signer that provides equivalent security to Cluster API v1alpha3. This is only to be used for
+    providers where no secure mechanism exists.
+
+- Core Cluster API MIGHT provide the following implementations of CSRs and signers:
+  - `cluster.x-k8s.io/kube-apiserver-client-kubelet-tpm` and `cluster-x-k8s-io/kubelet-serving-tpm`
+    - Will implement TPM-based certificate signers and requesters based on the
+      [cloud-provider-gcp implementation].
+    - We will additionally implement a challenge-response mechanism, similar to that done in
+      [SPIRE's TPM plugin]. This proposal will be updated with the implementation.
+    - However, since the mechanism for retrieving endorsement keys varies across
+    platforms, the TPM signer will additionally require a provider specific mechanism to provide the
+    TPM Endorsement Key's CA.
+
+#### Provider Specification
+
+##### All providers
+- All providers MUST insert a ProviderID within the KubernetesNodeProviderIdentifierOID extension
+  attribute of the CSR.
+- All signer names MUST be filled in by the provider’s controller in
+  InfraCluster.Status.KubeletClientCertificateSigner and
+  InfraCluster.Status.KubeletServingCertificateSigner if the attestation controller is running.
+- All providers SHOULD implement trust-on-first-use type mechanisms to prevent replay attacks. We
+  defer to providers how endpoint or authentication data is recorded to validate endpoints.
+
+##### Insecure providers
+- An insecure provider CANNOT implement certificate rotation or kubelet serving certificate signing.
+- InfraCluster.Status.KubeletClientCertificateSigner MUST be set to
+  cluster.x-k8s.io/kube-apiserver-client-kubelet-insecure.
+- An insecure provider MUST use the cluster.x-k8s.io/kube-apiserver-client-kubelet-insecure signer.
+
+##### Secure providers
+- A secure provider MUST implement certificate rotation and kubelet server certificate signing.
+- A provider must register signers of:
+    - `cluster-x-k8s-io/kube-apiserver-client-kubelet-<provider>`
+    - `cluster-x-k8s-io/kubelet-serving-<provider>`
+- A secure provider MUST implement a secure attestation mechanism, based upon PEM-encoded blocks
+  within the Certificate Signing Request.
+- Where a secure provider’s attestation mechanism does not include a challenge-response, nonce or
+  timestamp to protect against replay attacks, the mechanism MUST implement a secondary time-limited
+  attestation (e.g. AWS Instance Identity document + AWS HMACv4 signature).
+- A provider’s signer MUST run on the management cluster.
+
+##### TPM based providers
+- A TPM provider MUST use the following certificate signers
+    - `cluster-x-k8s-io/kube-apiserver-client-kubelet-tpm`
+    - `cluster-x-k8s-io/kubelet-serving-tpm`
+- A TPM provider MUST annotate new CSRs as follows:
+    - Key: cluster-x-k8s-io/tpm-endorsement-key
+  - Value: Platform-specific endorsement key (e.g., retrieved from GCP Shielded VM API or VMware
+    vCenter).
+
+#### Kubeadm
+Since this proposal essentially takes over part of the node registration process from kubeadm, we
+will require the following changes:
+- kubeadm COULD allow opt-out of kubeadm setting up ClusterRoleBindings between the system:nodes
+  group and the `system:certificates.k8s.io:certificatesigningrequests:selfnodeclient` permission,
+  so that certificate renewals must go through re-attestation.
+- Kubeadm COULD allow opt-out of kubeadm setting up `kubeadm:node-autoapprove-bootstrap` cluster
+  role binding. This is deferred to a future Kubeadm design and release, and for this proposal, we
+  will add fields to KubeadmControlPlane to remove these node groups and bindings post control plane
+  initialisation.
+
+The idea is to rely on the [client-go auth exec mechanism] of kubeconfigs with local cache
+directory, when kubelet wants to talk to the apiserver it will call on the kubelet authenticator to
+get a client certificate.
+
+#### Changes to the Cluster and core Cluster API controller
+
+``` yaml
+spec:
+  security:
+    kubeletAuthentication: true
+    authorizedAttestors:
+    - contosoCloud
+```
+
+#### Changes to KubeadmControlPlane resources and controller
+
+The cluster field if set will be read by KCP and remove the `kubeadm:node-autoapprove-bootstrap`
+cluster role binding.
+
+#### Changes to Cluster API Bootstrap Provider Kubeadm
+
+If the kubeletAuthentication field is set for the cluster, CABPK will
+default `--rotate-server-certificates` on NodeRegistrationOptions.ExtraArgs for the kubeadm
+configuration. If KubeletConfiguration is supported within Cluster API v1alpha4, we
+will opt to set ServerTLSBootstrap on KubeletConfiguration instead.
+
+CABPK will also update the runcmds for cloud-init / Ignition such that the authenticator is set up
+with the initial bootstrap token.
+
+##### Changes to token rotation
+
+Token rotation in CABPK is currently as follows:
+
+* If the token is for a Machine, renews the token TTL until the Machine has reached the
+  InfrastructureReady == True condition, at which point the TTL clock is run out.
+  * CABPK does not wait for Node Ready at present because we cannot ensure the machine bootstrap has
+    been deliberately interrupted such that it may be used to register an arbitrary node.
+* If the token is for a MachinePool, rotate the token when the TTL is hit.
+  * Since tokens are used for multiple machines to self-approve CSRs, we minimise token reuse
+    opportunities by rotating it.
+  * This causes issues for infrastructure provider mechanisms for MachinePools (User Story 2).
+
+When cluster.Spec.Security.KubeletAuthentication is set to true, CABPK will switch to this alternate
+behaviour, as there is no auto-approval of node CSRs:
+* If the token is for a Machine, renew the token TTL until the Machine is Ready (i.e. kubelet has
+  successfully registered and a ProviderID exists)
+* If the token is for a MachinePool, renew the token TTL for the lifetime of the MachinePool.
+  * This should be safe, as in the event of a compromise, administrators should replace the entire
+    MachinePool.
+
+
+#### Kubelet authenticator flow
+
+The authenticator will be responsible for updating the kubelet client certificates only.
+
+##### Client CSR flow
+
+![client auth](images/kubelet-authentication/client-authenticator-flow.png)
+
+##### Serving CSR handling
+
+For the Kubelet serving certificate, we intend to enable serving certificate TLS bootstrapping on
+Kubelet via the ServerTLSBootstrap settings of Kubelet's configuration.
+
+This will cause Kubelet to not generate a self-signed certificate for serving and instead
+submit CSRs for the initial certificate and rotation to the API server.
+
+The attestation controller will validate the following:
+
+* CSR spec.username field is of the form system:node:<nodeName> and spec.groups contains
+  system:nodes
+* Only contains digital signature, server auth and key encipherment usages.
+* Only has IP and DNS subjectAltNames that belong to the requesting node. We defer to
+  the infrastructure provider if it makes calls to the cloud provider for verification.
+
+### Risks and Mitigations
+
+There may be additional security risks being introduced in this design. In order to mitigate this,
+this proposal will be taken to SIG Security and SIG Auth for review **before the beta graduation**.
+
+## Alternatives
+
+#### Implement within the cloud providers instead of Cluster API
+Given that there is an existent implementation in cloud-provider-gcp, this could be extended to all
+of the cloud providers. However, there are some advantages to making Cluster API responsible for
+kubelet registration in that no changes to the assumptions around connectivity between management
+and workload clusters are required, neither does the signer need to be included as a static pod
+during control plane instantiation.
+
+#### Implement as authentication webhook, as per aws-iam-authenticator (Amazon EKS)
+If attestation was implemented as an authentication webhook, it would be in the critical path for
+all token-based authentication against the API server. It would also additionally be needed to be
+set up at workload cluster instantiation via a static pod and API server start up.
+
+#### SPIRE/SPIFFE
+
+SPIFFE (Secure Production Identity Framework for Everyone), and it's open source implementation in
+SPIRE form a set of standard frameworks for workload identity which is independent of any
+particular cluster technology. We spent some time investigating if SPIRE could be used as a baseline
+for kubelet authentication within Cluster API. However, [SPIRE currently requires a
+RDBMS][spire-architecture] independent of the Kubernetes API Server / etcd datastore. In the default
+mode, it uses SQLite.
+
+For the Day 0 provisioning of management clusters from Kind and then effecting a move of data, or
+otherwise bootstrapping SPIRE into a workload cluster on first boot presents a significant challenge
+as well as introducing a number of large dependencies into Cluster API. For this reason, we have
+chosen the main proposal instead.
+
+In addition, it isn't immediately clear how SVIDs (SANs starting with SPIFFE://\<identity\>) map to
+node identities accepted by the Kubernetes API Server. Node identity is most frequently the hostname
+in the CN of the certificate, and although there have been [initial discussions][spiffe-discussions]
+about how to make the Kubernetes API Server accept SVIDs directly, we do not want to wait on the
+resolution of that before proceeding.
+
+Where SPIFFE is desired end-to-end, it should in theory be possible to develop a CAPI kubelet
+authenticator provider that uses the SVID certificate as the CSR attestation data that is then
+exchanged for the kubelet certificate.
+
+## Upgrade Strategy
+
+upgrades should be transparent for users:
+
+- Upgrading cluster API components shouldn't have effects on existing clusters
+- Upgrading workload clusters should also work fine, as CABPK would supply a bootstrap script in
+  v1alpha4 and the current one when it's running in v1alpha3
+
+## Additional Details
+
+### Test Plan [optional]
+
+- E2E tests to be added to AWS, vSphere and Azure providers as each provider implements the signer
+- E2E tests to be added for the insecure signers for use with CAPD.
+Upgrade tests from latest minor release to latest main branch of Kubernetes
+
+
+### Graduation Criteria [optional]
+
+#### Graduation to beta
+- E2E tests testing upgrades to latest main branch of Kubernetes are required such that Cluster API
+  can make appropriate changes to node registration if kubelet or kubeadm behaviour changes.
+
+- Security review by SIG Auth and SIG Security
+#### Graduation to GA
+- External security review of the combined Cluster API and kubeadm model.
+
+
+### Version Skew Strategy
+
+Any changes to the attestation data should be handled in a backward compatible manner by the
+infrastructure provider when implementing the interface used by the node-attestation-controller, by
+making sure it's able to convert an older attestation format to a newer one.
+
+This will be done by the controller verifying the version of the CSR sent by the CLI. If the
+version is mismatched, the controller will add an annotation listing supported versions. If the
+CLI supports the older version, it files a new CSR with the older format.

+## Glossary
+
+### ClusterClass
+A collection of templates that define a topology (control plane and machine deployments) to be used to create one or more clusters.
+
+### Topology
+A topology refers to a Cluster that provides a single control point to manage its own topology; the topology is defined by a ClusterClass.
+
+### WorkerClass
+A collection of templates that define a set of worker nodes in the cluster. A ClusterClass contains zero or more WorkerClass definitions.
+
+
+## Summary
+
+This proposal introduces a new ClusterClass object which will be used to provide easy stamping of clusters of similar shapes. It serves as a collection of template resources which are used to generate one or more clusters of the same flavor.
+
+We're enhancing the Cluster CRD and controller to use a ClusterClass resource to provision the underlying objects that compose a cluster. Additionally, the Cluster provides a single control point to manage the Kubernetes version, worker pools, labels, replicas, and so on.
+
+## Motivation
+
+Currently, Cluster API does not expose a native way to provision multiple clusters of the same configuration. The ClusterClass object is supposed to act as a collection of template references which can be used to create managed topologies.
+
+Today, the Cluster object is a logical grouping of components which describe an underlying cluster. The user experience to create a cluster requires the user to create a bunch of underlying resources such as KCP (control plane provider), MachineDeployments, and infrastructure or bootstrap templates for those resources which logically end up representing the cluster. Since the cluster configuration is spread around multiple components, upgrading the cluster version is hard as it requires changes to different fields in different resources to perform an upgrade. The ClusterClass object aims at reducing this complexity by delegating the responsibility of lifecycle managing these underlying resources to the Cluster controller.
+
+This method of provisioning the cluster would act as a single control point for the entire cluster. Scaling the nodes, adding/removing sets of worker nodes and upgrading cluster kubernetes versions would be achievable by editing the topology. This would facilitate the maintenance of existing clusters as well as ease the creation of newer clusters.
+
+### Goals
+
+- Create the new ClusterClass CRD which can serve as a collection of templates to create clusters.
+- Extend the Cluster object to use ClusterClass for creating managed topologies.
+- Enhance the Cluster object to act as a single point of control for the topology.
+- Extend the Cluster controller to create/update/delete managed topologies.
+
+### Prospective future Work
+
+⚠️ The following points are mostly ideas and can change at any given time  ⚠️
+
+We are fully aware that in order to exploit the potential of ClusterClass and managed topologies, the following class of problems still needs to be addressed:
+- **Lifecycle of the ClusterClass**: Introduce mechanisms for allowing mutation of a ClusterClass, and the continuous reconciliation of the Cluster managed resources.
+- **Upgrade/rollback strategy**: Implement a strategy to upgrade and rollback the managed topologies.
+- **Extensibility/Transformation**: Introduce mechanism for allowing Cluster specific transformations of a ClusterClass (e.g. inject API Endpoint for CAPV, customize machine image by version etc.)
+- **Adoption**: Providing a way to convert existing clusters into managed topologies.
+- **Observability**: Build an SDK and enhance the Cluster object status to surface a summary of the status of the topology.
+- **Lifecycle integrations**: Extend ClusterClass to include lifecycle management integrations such as MachineHealthCheck and Cluster Autoscaler to manage the state and health of the managed topologies.
+
+However we are intentionally leaving them out from this initial iteration for the following reasons:
+- We want the community to reach a consensus on cornerstone elements of the design before iterating on additional features.
+- We want to enable starting the implementation of the required scaffolding and the initial support for managed topologies as soon as possible, so we can surface problems which are not easy to identify at this stage of the proposal.
+- We would like the community to rally in defining use cases for the advanced features, help in prioritizing them, so we can chart a more effective roadmap for the next steps.
+
+## Proposal
+
+This proposal enhances the `Cluster` object to create topologies using the `ClusterClass` object.
+
+### User Stories
+
+#### Story 1 - Use ClusterClass to easily stamp clusters
+As an end user, I want to use one `ClusterClass` to create multiple topologies of similar flavor.
+- Rather than recreating the KCP and MD objects for every cluster that needs to be provisioned, the end user can create a template once and reuse it to create multiple clusters with similar configurations.
+
+#### Story 2 - Easier UX for kubernetes version upgrades
+For an end user, the UX to update the kubernetes version of the control plane and worker nodes in the cluster should be easy.
+- Instead of individually modifying the KCP and each MachineDeployment, updating a single option should result in k8s version updates for all the CP and worker nodes.
+
+**Note**: In order to complete the user story for all the providers, some of the advanced features (such as Extensibility/Transformation) are required. However, getting this in place even only for a subset of providers allows us to build and test a big chunk of the entire machinery.
+
+#### Story 3 - Easier UX for scaling workers nodes
+As an end user, I want to be able to easily scale up/down the number of replicas for each set of worker nodes in the cluster.
+- Currently, (for a cluster with 3 machine deployments) this is possible by updating these three different objects representing the sets of worker nodes in the pool. An easier user experience would be to update a single object to enable the scaling of multiple sets of worker nodes.
+
+### Implementation Details/Notes/Constraints
+
+The following section provides details about the introduction of new types and modifications to existing types to implement the ClusterClass functionality.
+If instead you are eager to see an example of ClusterClass and how the Cluster object will look like, you can jump to the Behavior paragraph.
+
+#### New API types
+##### ClusterClass
+This CRD is a collection of templates that describe the topology for one or more clusters.
+```golang
+// +kubebuilder:object:root=true
+// +kubebuilder:resource:path=clusterclasses,shortName=cc,scope=Namespaced,categories=cluster-api
+// +kubebuilder:storageversion
+
+// ClusterClass is a template which can be used to create managed topologies.
+type ClusterClass struct {
+  metav1.TypeMeta   `json:",inline"`
+  metav1.ObjectMeta `json:"metadata,omitempty"`
+
+  Spec ClusterClassSpec `json:"spec,omitempty"`
+}
+
+// ClusterClassSpec describes the desired state of the ClusterClass.
+type ClusterClassSpec struct {
+  // Infrastructure is a reference to a provider-specific template that holds
+  // the details for provisioning infrastructure specific cluster
+  // for the underlying provider.
+  // The underlying provider is responsible for the implementation
+  // of the template to an infrastructure cluster.
+  Infrastructure LocalObjectTemplate `json:"infrastructure,omitempty"`
+
+  // ControlPlane is a reference to a local struct that holds the details
+  // for provisioning the Control Plane for the Cluster.
+  ControlPlane ControlPlaneClass `json:"controlPlane,omitempty"`
+
+  // Workers describes the worker nodes for the cluster.
+  // It is a collection of node types which can be used to create
+  // the worker nodes of the cluster.
+  // +optional
+  Workers WorkersClass `json:"workers,omitempty"`
+}
+
+// ControlPlaneClass defines the class for the control plane.
+type ControlPlaneClass struct {
+	Metadata ObjectMeta `json:"metadata,omitempty"`
+
+	// LocalObjectTemplate contains the reference to the control plane provider.
+	LocalObjectTemplate `json:",inline"`
+
+	// MachineTemplate defines the metadata and infrastructure information
+	// for control plane machines.
+	//
+	// This field is supported if and only if the control plane provider template
+	// referenced above is Machine based and supports setting replicas.
+	//
+	// +optional
+	MachineInfrastructure *LocalObjectTemplate `json:"machineInfrastructure,omitempty"`
+}
+
+// WorkersClass is a collection of deployment classes.
+type WorkersClass struct {
+  // MachineDeployments is a list of machine deployment classes that can be used to create
+  // a set of worker nodes.
+  MachineDeployments []MachineDeploymentClass `json:"machineDeployments,omitempty"`
+}
+
+// MachineDeploymentClass serves as a template to define a set of worker nodes of the cluster
+// provisioned using the `ClusterClass`.
+type MachineDeploymentClass struct {
+  // Class denotes a type of worker node present in the cluster,
+  // this name MUST be unique within a ClusterClass and can be referenced
+  // in the Cluster to create a managed MachineDeployment.
+  Class string `json:"class"`
+
+  // Template is a local struct containing a collection of templates for creation of
+  // MachineDeployment objects representing a set of worker nodes.
+  Template MachineDeploymentClassTemplate `json:"template"`
+}
+
+// MachineDeploymentClassTemplate defines how a MachineDeployment generated from a MachineDeploymentClass
+// should look like.
+type MachineDeploymentClassTemplate struct {
+  Metadata ObjectMeta `json:"metadata,omitempty"`
+
+  // Bootstrap contains the bootstrap template reference to be used
+  // for the creation of worker Machines.
+  Bootstrap LocalObjectTemplate `json:"bootstrap"`
+
+  // Infrastructure contains the infrastructure template reference to be used
+  // for the creation of worker Machines.
+  Infrastructure LocalObjectTemplate `json:"infrastructure"`
+}
+
+// LocalObjectTemplate defines a template for a topology Class.
+type LocalObjectTemplate struct {
+  // Ref is a required reference to a custom resource
+  // offered by a provider.
+  Ref *corev1.ObjectReference `json:"ref"`
+}
+```
+
+#### Modification to existing API Types
+##### Cluster
+1.  Add `Cluster.Spec.Topology` defined as
+    ```golang
+    // This encapsulates the topology for the cluster.
+	// NOTE: This feature is alpha; it is required to enable the ClusterTopology
+	// feature gate flag to activate managed topologies support.
+	// +optional
+	Topology *Topology `json:"topology,omitempty"`
+    ```
+1.  The `Topology` object has the following definition:
+    ```golang
+    // Topology encapsulates the information of the managed resources.
+    type Topology struct {
+      // The name of the ClusterClass object to create the topology.
+      Class string `json:"class"`
+
+	  // The kubernetes version of the cluster.
+	  Version string `json:"version"`
+
+	  // RolloutAfter performs a rollout of the entire cluster one component at a time,
+	  // control plane first and then machine deployments.
+	  // +optional
+	  RolloutAfter *metav1.Time `json:"rolloutAfter,omitempty"`
+
+	  // The information for the Control plane of the cluster.
+	  ControlPlane ControlPlaneTopology `json:"controlPlane"`
+
+	  // Workers encapsulates the different constructs that form the worker nodes
+	  // for the cluster.
+	  // +optional
+	  Workers *WorkersTopology `json:"workers,omitempty"`
+    }
+    ```
+1.  The `ControlPlaneTopology` object contains the parameters for the control plane nodes of the topology.
+    ```golang
+    // ControlPlaneTopology specifies the parameters for the control plane nodes in the cluster.
+    type ControlPlaneTopology struct {
+      Metadata ObjectMeta `json:"metadata,omitempty"`
+
+      // The number of control plane nodes.
+      // If the value is nil, the ControlPlane object is created without the number of Replicas
+      // and it's assumed that the control plane controller does not implement support for this field.
+      // When specified against a control plane provider that lacks support for this field, this value will be ignored.
+      // +optional
+      Replicas *int `json:"replicas,omitempty"`
+    }
+    ```
+1.  The `WorkersTopology` object represents the sets of worker nodes of the topology.
+
+    **Note**: In this proposal, a set of worker nodes is handled by a MachineDeployment object. In the future, this can be extended to include Machine Pools as another backing mechanism for managing worker node sets.
+    ```golang
+    // WorkersTopology represents the different sets of worker nodes in the cluster.
+    type WorkersTopology struct {
+      // MachineDeployments is a list of machine deployment in the cluster.
+      MachineDeployments []MachineDeploymentTopology `json:"machineDeployments,omitempty"`
+    }
+    ```
+1.  The `MachineDeploymentTopology` object represents a single set of worker nodes of the topology.
+    ```golang
+    // MachineDeploymentTopology specifies the different parameters for a set of worker nodes in the topology.
+    // This set of nodes is managed by a MachineDeployment object whose lifecycle is managed by the Cluster controller.
+    type MachineDeploymentTopology struct {
+    Metadata ObjectMeta `json:"metadata,omitempty"`
+
+      // Class is the name of the MachineDeploymentClass used to create the set of worker nodes.
+      // This should match one of the deployment classes defined in the ClusterClass object
+      // mentioned in the `Cluster.Spec.Class` field.
+      Class string `json:"class"`
+
+      // Name is the unique identifier for this MachineDeploymentTopology.
+      // The value is used with other unique identifiers to create a MachineDeployment's Name
+      // (e.g. cluster's name, etc). In case the name is greater than the allowed maximum length,
+      // the values are hashed together.
+      Name string `json:"name"`
+
+      // The number of worker nodes belonging to this set.
+      // If the value is nil, the MachineDeployment is created without the number of Replicas (defaulting to zero)
+      // and it's assumed that an external entity (like cluster autoscaler) is responsible for the management
+      // of this value.
+      // +optional
+      Replicas *int `json:"replicas,omitempty"`
+    }
+    ```
+
+#### Validations
+##### ClusterClass
+- For object creation:
+  - (defaulting) if namespace field is empty for a reference, default it to `metadata.Namespace`
+  - all the reference must be in the same namespace of `metadata.Namespace`
+  - `spec.workers.machineDeployments[i].class` field must be unique within a ClusterClass.
+- For object updates:
+  - all the reference must be in the same namespace of `metadata.Namespace`
+  - `spec.workers.machineDeployments[i].class` field must be unique within a ClusterClass.
+  - `spec.workers.machineDeployments` supports adding new deployment classes.
+
+##### Cluster
+- For object creation:
+  - `spec.topology` and `spec.infrastructureRef` cannot be simultaneously set.
+  - `spec.topology` and `spec.controlPlaneRef` cannot be simultaneously set.
+  - If `spec.topology` is set, `spec.topology.class` cannot be empty.
+  - If `spec.topology` is set, `spec.topology.version` cannot be empty and must be a valid semver.
+  - `spec.topology.workers.machineDeployments[i].name` field must be unique within a Cluster
+
+- For object updates:
+  - If `spec.topology.class` is set it cannot be unset or modified, and if it's unset it cannot be set.
+  - `spec.topology.version` cannot be unset and must be a valid semver, if being updated.
+  - `spec.topology.version` cannot be downgraded.
+  - `spec.topology.workers.machineDeployments[i].name` field must be unique within a Cluster
+  - A set of worker nodes can be added to or removed from the `spec.topology.workers.machineDeployments` list.
+
+##### ClusterClass compatibility
+There are cases where we must consider whether two ClusterClasses are compatible:
+1. Where a user chooses to replace an existing ClusterClass `cluster.spec.topology.class` with a new ClusterClass.
+2. Where a user updates a ClusterClass currently in use by a Cluster.
+
+To establish compatibility between two ClusterClasses:
+    - All the references must be in the same namespace of `metadata.Namespace` - the same namespace as the existing clusterClass.
+    - `spec.workers.machineDeployments` must not remove any deployment classes (adding new or modifying existing classes is supported).
+    - `spec.controlPlane.localobjecttemplate`, `spec.controlplane.machineinfrastructure`, `spec.infrastructure`,  `spec.workers.machineDeployments[].template.infrastructure.ref` must not change apiGroup or Kind.
+
+#### Behaviors
+This section lists out the behavior for Cluster objects using `ClusterClass` in case of creates and updates.
+
+##### Create a new Cluster using ClusterClass object
+1. User creates a ClusterClass object.
+   ```yaml
+    apiVersion: cluster.x-k8s.io/v1alpha4
+    kind: ClusterClass
+    metadata:
+      name: mixed
+      namespace: bar
+    spec:
+      controlPlane:
+        ref:
+          apiVersion: controlplane.cluster.x-k8s.io/v1alpha4
+          kind: KubeadmControlPlaneTemplate
+          name: vsphere-prod-cluster-template-kcp
+      workers:
+        deployments:
+        - class: linux-worker
+          template:
+            bootstrap:
+              ref:
+                apiVersion: bootstrap.cluster.x-k8s.io/v1alpha4
+                kind: KubeadmConfigTemplate
+                name: existing-boot-ref
+            infrastructure:
+              ref:
+                apiVersion: infrastructure.cluster.x-k8s.io/v1alpha4
+                kind: VSphereMachineTemplate
+                name: linux-vsphere-template
+        - class: windows-worker
+          template:
+            bootstrap:
+              ref:
+                apiVersion: bootstrap.cluster.x-k8s.io/v1alpha4
+                kind: KubeadmConfigTemplate
+                name: existing-boot-ref-windows
+            infrastructure:
+              ref:
+                apiVersion: infrastructure.cluster.x-k8s.io/v1alpha4
+                kind: VSphereMachineTemplate
+                name: windows-vsphere-template
+      infrastructure:
+        ref:
+          apiVersion: infrastructure.cluster.x-k8s.io/v1alpha4
+          kind: VSphereClusterTemplate
+          name: vsphere-prod-cluster-template
+   ```
+2. User creates a cluster using the class name and defining the topology.
+   ```yaml
+    apiVersion: cluster.x-k8s.io/v1alpha4
+    kind: Cluster
+    metadata:
+      name: foo
+      namespace: bar
+    spec:
+      topology:
+        class: mixed
+        version: v1.19.1
+        controlPlane:
+          replicas: 3
+          labels: {}
+          annotations: {}
+        workers:
+          machineDeployments:
+          - class: linux-worker
+            name: big-pool-of-machines-1
+            replicas: 5
+            labels:
+              # This label is additive to the class' labels,
+              # or if the same label exists, it overwrites it.
+              custom-label: "production"
+          - class: linux-worker
+            name: small-pool-of-machines-1
+            replicas: 1
+          - class: windows-worker
+            name: microsoft-1
+            replicas: 3
+   ```
+3. The Cluster controller checks for the presence of the `spec.topology.class` field. If the field is missing, the Cluster controller behaves in the existing way. Otherwise the controller starts the creation process of the topology defined in the steps below.
+4. Cluster and Control plane object creation
+    1. Creates the infrastructure provider specific cluster using the cluster template referenced in the `ClusterClass.spec.infrastructure.ref` field.
+    1. Add the topology label to the provider cluster object:
+       ```yaml
+        topology.cluster.x-k8s.io/owned: ""
+       ```
+    1. For the ControlPlane object in `cluster.spec.topology.controlPlane`
+    1. Initializes a control plane object using the control plane template defined in the `ClusterClass.spec.controlPlane.ref field`. Use the name `<cluster-name>`.
+    1. If `spec.topology.controlPlane.replicas` is set, set the number of replicas on the control plane object to that value.
+    1. Sets the k8s version on the control plane object from the `spec.topology.version`.
+    1. Add the following labels to the control plane object:
+       ```yaml
+        topology.cluster.x-k8s.io/owned: ""
+       ```
+    1. Creates the control plane object.
+    1. Sets the `spec.infrastructureRef` and `spec.controlPlaneRef` fields for the Cluster object.
+    1. Saves the cluster object in the API server.
+5. Machine deployment object creation
+    1. For each `spec.topology.workers.machineDeployments` item in the list
+    1. Create a name `<cluster-name>-<worker-set-name>` (if too long, hash it)
+    1. Initializes a new MachineDeployment object.
+    1. Sets the `clusterName` field on the MD object
+    1. Sets the `replicas` field on the MD object using `replicas` field for the set of worker nodes.
+    1. Sets the `version` field on the MD object from the `spec.topology.version`.
+    1. Sets the `spec.template.spec.bootstrap` on the MD object from the `ClusterClass.spec.workers.machineDeployments[i].template.bootstrap.ref` field.
+    1. Sets the `spec.template.spec.infrastructureRef` on the MD object from the `ClusterClass.spec.workers.machineDeployments[i].template.infrastructure.ref` field.
+    1. Generates the set of labels to be set on the MD object. The labels are additive to the class' labels list, and the value in the `spec.topology.workers.machineDeployments[i].labels` takes precedence over any set by the ClusterClass. Include the topology label as well as a label to track the name of the MachineDeployment topology:
+       ```yaml
+        topology.cluster.x-k8s.io/owned: ""
+        topology.cluster.x-k8s.io/deployment-name: <machine-deployment-topology-name>
+       ```
+      Note: The topology label needs to be set on the individual Machine objects as well.
+    1. Creates the Machine Deployment object in the API server.
+
+![Creation of cluster with ClusterClass](./images/cluster-class/create.png)
+
+##### Update an existing Cluster using ClusterClass
+This section talks about updating a cluster which was created using a `ClusterClass` object.
+1. User updates the `cluster.spec.topology` field adhering to the update validation [criteria](#clusterclass-2).
+2. For the ControlPlane object in `spec.topology.controlPlane`, the cluster controller checks for the presence of the control plane object using the name `<cluster-name>`. If found,
+    1. Compares and updates the number of replicas, if necessary.
+    1. Compares and updates the k8s version, if necessary.
+    1. Updates the KCP object in the API server.
+3. The cluster controller reconciles the list of required machine deployments with the current list of managed machine deployments by:
+    1. Adding/Removing MachineDeployment if necessary.
+    1. Comparing and updating the number of replicas, if necessary.
+    1. Comparing and updating the k8s version for the MD, if necessary.
+    1. Updating the Machine Deployment object in the API server.

+
+#### Provider implementation
+
+**Impact on the bootstrap providers**:
+- None.
+
+**Impact on the controlPlane providers**:
+- the provider implementers are required to implement the ControlPlaneTemplate type (e.g. `KubeadmControlPlaneTemplate` etc.).
+- it is also important to notice that:
+    - ClusterClass and managed topologies can work **only** with control plane providers implementing support for the `spec.version` field;
+      Additionally, it is required to provide support for the `status.version` field reporting the minimum
+      API server version in the cluster as required by the control plane contract.
+    - ClusterClass and managed topologies can work both with control plane providers implementing support for
+      machine infrastructures and with control plane providers not supporting this feature.
+      Please refer to the control plane for the list of well known fields where the machine template
+      should be defined (in case this feature is supported).
+    - ClusterClass and managed topologies can work both with control plane providers implementing support for
+      `spec.replicas` and with control plane provider not supporting this feature.
+
+**Impact on the infrastructure providers**:
+
+- the provider implementers are required to implement the InfrastructureClusterTemplate type (e.g. `AWSClusterTemplate`, `AzureClusterTemplate` etc.).
+
+#### Conventions for template types implementation
+
+Given that it is required to implement new templates, let's remind the conventions used for
+defining templates and the corresponding objects:
+
+Templates:
+
+- Template fields must match or be a subset of the corresponding generated object.
+- A template can't accept values which are not valid for the corresponding generated object,
+  otherwise creating an object derived from a template will fail.
+  
+Objects generated from the template:
+
+- For the fields existing both in the object and in the corresponding template:
+    - The object can't have additional validation rules than the template,
+      otherwise creating an object derived from a template could fail.
+    - It is recommended to use the same defaulting rules implemented in the template,
+      thus avoiding confusion in the users.
+- For the fields existing only in the object but not in the corresponding template:
+    - Fields must be optional or a default value must be automatically assigned,
+      otherwise creating an object derived from a template will fail.
+
+**Note:** The existing InfrastructureMachineTemplate and BootstrapMachineTemplate objects already
+comply those conventions via explicit rules implemented in the code or via operational practices
+(otherwise creating machines would not be working already today).
+
+**Note:** As per this proposal, the definition of ClusterClass is immutable. The CC definition consists 
+of infrastructure object references, say AWSMachineTemplate, which could be immutable. For such immutable
+infrastructure objects, hard-coding the image identifiers leads to those templates being tied to a particular
+Kubernetes version, thus making Kubernetes version upgrades impossible. Hence, when using CC, infrastructure
+objects MUST NOT have mandatory static fields whose values prohibit version upgrades.
+
+#### Notes on template <-> object reconciliation
+
+One of the key points of this proposal is that cluster topologies are continuously
+reconciled with the original templates to ensure consistency over time and to support changing the generated
+topology when necessary.
+
+Cluster Class and managed topologies reconciliation leverages on the conventions for template types documented in the previous
+paragraph and on the [Kubernetes API conventions](https://github.com/kubernetes/community/blob/master/contributors/devel/sig-architecture/api-conventions.md)
+in order to reconcile objects in the cluster with the corresponding templates in the ClusterClass.
+
+The reconciliation process enforces that all the fields in the template for which a value is defined are reflected in the object.
+
+In practice:
+- If a field has a value in the template, but the users/another controller changes the value for this field in the object, the reconcile
+  topology process will restore the field value from the template; please note that due to how merge patches works internally:
+    - In case the field is a map, the reconcile process enforces the map entries from the template, but additional map entries
+      are preserved.
+    - In case the field is a slice, the reconcile process enforces the slice entries from the template, while additional values
+      are deleted.
+
+Please note that:
+- If a field does not have a value in the template, but the users/another controller sets this value in the object,
+  the reconcile topology process will preserve the field value.
+- If a field does not exist in the template, but it exists only in the object, and the users/another controller
+  sets this field's value, the reconcile topology process will preserve it.
+- If a field is defined as `omitempty` but the field type is not a pointer or a type that has a built-in nil value, 
+  e.g a `Field1 bool 'json:"field1,omitempty"'`, it won't be possible to enforce the zero value in the template for the field, 
+  e.g `field1: false`, because the field is going to be removed and technically there is no way to distinguishing
+  unset from the zero value for that type.
+  NOTE: this is a combination not compliant with the recommendations in the [Kubernetes API conventions](https://github.com/kubernetes/community/blob/master/contributors/devel/sig-architecture/api-conventions.md#optional-vs-required)).
+- If a field is defined as `omitempty` and the field type is a pointer or a type that has a built-in nil value,
+  e.g a `Field1 *bool 'json:"field1,omitempty"'`, it will be possible to enforce the zero value in the template 
+  for the field, e.g `field1: false` (but it won't be possible to enforce `field1: null`).
+
+### Risks and Mitigations
+
+This proposal tries to model the API design for ClusterClass with a narrow set of use cases. This initial implementation provides a baseline on which incremental changes can be introduced in the future. Instead of encompassing of all use cases under a single proposal, this proposal mitigates the risk of waiting too long to consider all required use cases under this topic.
+
+## Alternatives
+
+## Upgrade Strategy
+
+Existing clusters created without ClusterClass cannot switch over to using ClusterClass for a topology.
+
+## Additional Details
+
+### Test Plan [optional]
+
+TBD
+
+### Graduation Criteria [optional]
+
+The initial plan is to rollout Cluster Class and support for managed topologies under a feature flag which would be unset by default.

 - __Infrastructure provider__: Refers to the source of computational resources (e.g. machines, networking, etc.). Examples for cloud include AWS, Azure, Google, etc.; for bare metal include VMware, MAAS, etc. When there is more than one way to obtain resources from the same infrastructure provider (e.g. EC2 vs. EKS) each way is referred to as a variant.

+# Cert-manager
+
+This extension deploys cert-manager.
+
+## Usage
+
+Basic usage
+
+```
+load('ext://cert_manager', 'deploy_cert_manager')
+
+deploy_cert_manager()
+```
+
+This will deploy cert-manager to your cluster and check that it actually works.
+
+If working with Kind, it's possible to pass `load_to_kind=True` to `deploy_cert_manager` so
+all the cert-manager images will be pre-pulled to your local environment and then loaded into Kind before installing.
+This speeds up your workflow if you're repeatedly destroying and recreating your kind cluster, as it doesn't
+have to pull the images over the network each time.
+
+The full list of parameters accepted by `deploy_cert_manager` includes:
+- `registry` from which images should be pulled, defaults to `quay.io/jetstack`
+- `version` of cert-manager to install, defaults to `v1.3.1`
+- `load_to_kind` (see above), defaults to `False`
+- `kind_cluster_name`, defaults to `kind`
